Coach: Slaven Bilic
Star player: Luka Modric
Previous appearances: 1996 (quarter-finals), 2004 (first round), 2008 (quarter-finals)
Chances: Were strong favourites to win what appeared an easy qualifying group but a shock defeat in Georgia and one point from their two games with Greece forced them into the play-offs, where they cruised past Turkey. Boast one of the most sought-after players around in Modric but not the force they were in the 1990s.
Coach: Michal Bilek
Star player: Petr Cech
Previous appearances: 1960 (third place*), 1976 (winners*), 1980 (third place*), 1996 (runners-up), 2000 (first round), 2004 (semi-finals), 2008 (first round)
Chances: Lucky even to reach the play-offs after a controversial penalty got them a draw in Scotland. The Czechs look a shadow of the side that lit up Euro 96 and Euro 2004 and it would be a major shock were they to get out of anything but the kindest of groups.
Coach: Morten Olsen
Star player: Christian Eriksen
Previous appearances: 1964 (semi-finals), 1984 (semi-finals), 1988 (first round), 1992 (winners), 1996 (first round), 2000 (first round), 2004 (quarter-finals)
Chances: Put a wretched 2010 behind them with a hugely impressive 2011, which saw them take 16 points from their six qualifiers to overhaul Portugal at the top of Group H, winning the sides' Copenhagen showdown last month. But the 1992 European champions will have their work cut out to reach the knockout phase in Poland and Ukraine.
Coach: Fabio Capello
Star player: Wayne Rooney
Previous appearances: 1968 (third place), 1980 (first round), 1988 (first round), 1992 (first round), 1996 (semi-finals), 2000 (first round), 2004 (quarter-finals)
Chances: England's hopes could ultimately rest on whether Rooney's ban - which currently rules him out of the group stages - is reduced. Dismal performances at the last two World Cups and failure to reach Euro 2008 have left fans disillusioned but Capello does have the players to get to the last eight and beyond.
Coach: Laurent Blanc
Star player: Samir Nasri
Previous appearances: 1960 (fourth place), 1984 (winners), 1992 (first round), 1996 (semi-finals), 2000 (winners), 2004 (quarter-finals), 2008 (first round)
Chances: Narrowly avoided the play-offs after scraping a home draw with Bosnia-Herzegovina, France are nevertheless unbeaten in 17 games. Their biggest enemy in Poland and Ukraine is likely to be themselves, as shown by their mutinous 2010 World Cup campaign, but they have the talent to reach the semi-finals.
Coach: Joachim Low
Star player: Mesut Ozil
Previous appearances: 1972 (winners*), 1976 (runners-up*), 1980 (winners*), 1984 (first round*), 1988 (semi-finals*), 1992 (runners-up) 1996 (winners), 2000 (first round), 2004 (first round), 2008 (runners-up).
* As West Germany
Chances: Romped through qualifying, scoring a whopping 34 goals in 10 straight victories. Joachim Low's men look to have improved since being beaten by Spain in the last two major championships. They must be favourites among the sides looking to stop the Spaniards completing a hat-trick of triumphs.
Coach: Fernando Santos
Star player: Sotiris Ninis
Previous appearances: 1980 (first round), 2004 (winners), 2008 (first round)
Chances: If Greece managed to win Euro 2004, anything is possible. Like seven years ago, they go into next summer's tournament on an impressive run of form, with new boss Fernando Santos unbeaten in 17 matches until the friendly defeat to Romania. However, they have yet to play a big nation under Santos and it is hard to imagine them reaching the quarter-finals.
Coach: Bert van Marwijk
Star player: Wesley Sneijder
Previous appearances: 1976 (third place), 1980 (first round), 1988 (winners), 1992 (semi-finals), 1996 (quarter-finals), 2000 (semi-finals) 2004 (semi-finals), 2008 (quarter-finals)
Chances: Looked set for the best qualifying record of any country until they lost their final Group E match in Sweden. Still finished as top scorers - albeit with 16 of their 37 goals coming against San Marino. A strong team ethic took them all the way to the World Cup final last year and few would bet against them repeating the trick in Poland and Ukraine.
Coach: Cesare Prandelli
Star player: Gianluigi Buffon
Previous appearances: 1968 (winners), 1980 (fourth place), 1988 (semi-finals), 1996 (first round), 2000 (runners-up) 2004 (first round), 2008 (quarter-finals)
Chances: Boasting the stingiest rearguard in qualifying with just two goals conceded, Italy's strength clearly continues to lie at the back, despite something of a changing of the guard since their disappointing World Cup defence. They showed their potential by beating Spain recently and will be expecting to reach the semi-finals at least next summer.
Coach: Franciszek Smuda
Star player: Jakub Blaszczykowski
Previous appearances: 2008 (first round)
Chances: They might have struggled to qualify were they not co-hosting the tournament but home advantage means Poland cannot be completely written off. Their long build-up of friendlies has included a victory over Argentina and a draw with Germany but also defeats to Lithuania and Australia, which suggest they may not get out of their group.
Coach: Paulo Bento
Star player: Cristiano Ronaldo
Previous appearances: 1984 (semi-finals), 1996 (quarter-finals), 2004 (runners-up), 2008 (quarter-finals)
Chances: Condemned to the play-offs after losing their final winner-takes-all qualifier in Denmark. Full of goals, as they proved by thrashing Bosnia-Herzegovina 6-2 to reach the finals, and have the best player at the tournament in Ronaldo, on club form at any rate. But enough doubts remain defensively to make them unlikely champions.
REPUBLIC OF IRELAND
Coach: Giovanni Trapattoni
Star player: Shay Given
Previous appearances: 1988 (first round).
Chances: After so many European Championship qualifying failures and the handball storm which cost them a place at the 2010 World Cup, Ireland finally have something to celebrate again. They took full advantage of a dream play-off draw against Estonia and, despite being fourth seeds, expect them to cause an upset or two in Poland and Ukraine.
Coach: Dick Advocaat
Star player: Andrey Arshavin
Previous appearances: 1960 (winners*), 1964 (runners-up*), 1968 (fourth place*), 1972 (runners-up*), 1988 (runners-up*), 1992* (first round), 1996 (first round), 2004 (first round), 2008 (semi-finals).
* As USSR or CIS.
Chances: Took Euro 2008 by storm before being knocked out by eventual champions Spain, it is hard to see them repeating the trick after being pushed all the way by Ireland in qualifying Group B. A quarter-final berth would be a major success.
Coach: Vicente Del Bosque
Star man: Xavi
Previous appearances: 1964 (winners), 1980 (first round), 1984 (runners-up), 1988 (first round), 1996 (quarter-finals), 2000 (quarter-finals) 2004 (first round), 2008 (winners).
Chances: Not invincible - as Argentina, Portugal, Italy and England have all demonstrated since the World Cup - but still probably the best team on the planet and favourites to make it a hat-trick of major championship wins. If they play like they can, they may be almost impossible to stop.
Coach: Erik Hamren
Star man: Zlatan Ibrahimovic
Previous appearances: 1992 (semi-finals), 2000 (first round) 2004 (quarter-finals), 2008 (first round).
Chances: Sweden continue to punch above their weight at international level, ruining Holland's perfect qualifying record in their final Group E game to reach Poland and Ukraine as the best runners-up. Their 31 goals was the third-highest total of the campaign as they made amends for their failure to reach the World Cup. But a quarter-final next summer is the limit of their ambitions.
Coach: Oleg Blokhin
Star man: Andriy Shevchenko
Previous appearances: None.
Chances: Had Ukraine been hosting this tournament six years ago, they might have been considered dark horses. But their travails in the build-up to next summer's tournament were summed up in April when they reappointed the man who took them to their only previous major championship, Oleg Blokhin, as manager. A quarter-final spot would be a major achievement.
