Tottenham boss Mauricio Pochettino thinks his young side can challenge for the Premier League title, but insists they must not get carried away with their good form.
Pochettino was speaking after Spurs beat Watford 2-1 at Vicarage Road on Monday, where a late winner from Heung-Min Son secured a third victory on the trot.
The north Londoners have close to within four points of top spot and head into the New Year in the top-four, after losing just two of their opening 19 league games.
Pochettino reckons they could be title contenders come the end of the season, although he stressed the players must continue to graft in the second half of the season or risk undoing all their hard work.
"I think that the numbers reflect that it [the title] is always possible," the Argentine said in his post-match press conference.
"But the most important thing for us is to keep working very hard, because we are very young. You need to show the strength during the whole season and, if we start to speak today about the title, it is still most important to work hard and show in every game what we showed today.
"It was a fantastic victory because a few weeks ago Liverpool had a lot of problems here and lost 3-0. We came here and we were unlucky to concede a goal, on a difficult pitch because the grass was bad.
"It's very important to keep our feet on the ground. We have very clever and smart players that are available to learn about football. The key is to keep behaving in the same way as we did six months ago when we started the league."
