Liverpool's last-gasp failure to land Ukraine forward Konoplyanka looked set to become the biggest story of a relatively low-key transfer deadline day.
Konoplyanka was widely reported to be undergoing a medical with the club before his projected £15million switch from Dnipro Dnipropetrovsk hit complications.
The apparent breakdown of the deal left Reds boss Brendan Rodgers empty-handed on a day when Premier League title rivals Chelsea looked to the future.
Jose Mourinho moved to land 19-year-old St Etienne defender Kurt Zouma on a five-and-a-half year deal - but the player will remain at his current club until at least the end of the season.
Mourinho said: "If we don't do it now, probably we can't do it in the summer because other clubs were also very strong on him.
"He's another young player in the profile of some Chelsea signed in the couple of last years. He is a young player for a position where we also need the future."
Meanwhile Chelsea confirmed Gael Kakuta has joined Serie A Lazio on loan until the end of the season.
Arsene Wenger moved to strengthen Arsenal's Barclays Premier League title push by sealing the loan signing of Spartak Moscow midfielder Kim Kallstrom until the end of the season.
The 31-year-old has made 108 international appearances for Sweden and played more than 400 club matches during spells in his homeland, France and Russia.
Wenger's move came shortly after the Gunners dropped their interest in German attacking midfielder Julian Draxler, and the Arsenal boss said he was delighted to have got his man.
Wenger said: "Kim Kallstrom is a hugely experienced player.
"He is a midfielder with proven quality at both club and international level. We welcome Kim to Arsenal."
Leaving the Gunners is midfielder Emmanuel Frimpong, who has joined Championship side Barnsley in a permanent deal.
Dimitar Berbatov's colourful Premier League career could have come to a close after eight years as he left Fulham to join Ligue 1 title challengers Monaco on loan until the end of the season.
The 33-year-old, whose contract with the Cottagers expires in the summer, told Monaco's official website, www.asm-fc.com: "I'm happy, excited and a little bit nervous to be honest."
Fulham boss Rene Meulensteen responded by signing Lewis Holtby and John Heitinga on loan from Tottenham and Everton respectively, and Greek striker Kostas Mitroglou from Olympiacos for an undisclosed fee.
Crystal Palace snapped up Celtic midfielder Joe Ledley and Blackburn defender Scott Dann on permanent deals, and signed highly-rated Blackpool winger Tom Ince on loan until the end of the season.
In addition Eagles boss Tony Pulis has brought in Wolves goalkeeper Wayne Hennessey and turned Jason Puncheon's loan move from Southampton into a permanent deal.
Dani Osvaldo's ill-fated five-month stay at Southampton is over, with the Saints' club-record signing joining Juventus on loan with a view to a permanent move.
Much had been expected of the 28-year-old after he swapped Roma for the south coast in August in a deal worth up to £14.6million.
The Italy international penned a four-year deal but managed just 166 days at St Mary's, with Saints cutting their losses after an altercation with team-mate Jose Fonte last week.
"Juventus Football Club can today confirm that terms have been agreed with Southampton Football Club on a free loan deal for Pablo Daniel Osvaldo," the club said on their official website, www.juventus.com.
"The agreement also includes the option, to be exercised before May 13 2014, for the purchase of the player's full registration rights at a price of 19million euros, to be paid over the course of three years."
There were no moves for Joleon Lescott - who took to Twitter to deny rumours of an impending departure from Manchester City - or Sunderland midfielder Lee Cattermole, whose move to Stoke fell through despite reports of a fee having been agreed.
Black Cats boss Gus Poyet has strengthened his squad by signing Scotland midfielder Liam Bridcutt from Brighton on a three and a half year deal for an undisclosed fee.
Meanwhile, the long-anticipated loan deal for Manchester United winger Wilfried Zaha to Cardiff has finally gone through.
The 21-year-old has joined the Bluebirds for the rest of the season and should get a chance to prove his Premier League quality after a frustrating six months at United.
