Tottenham Hotspur manager Mauricio Pochettino has told Sky Sports that he thinks Spurs need to sign players in the January transfer window – before 'bigger' clubs pursue in the summer.

Spurs looked to be on course for an impressive season as they were riding high in the Premier League and took four points off Real Madrid in the Champions League, but that feeling has changed in recent weeks.

Whilst Spurs have blitzed through their Champions League group, finishing up with a 3-0 home win over APOEL Nicosia in midweek, they have failed to win any of their last four Premier League games, taking just two points in that run.

Suddenly, Spurs now lie 18 points adrift of league leaders Manchester City, and appear to be out of the title race, with manager Pochettino now searching for answers.

Ahead of today's game with Stoke City, manager Pochettino has discussed the upcoming January transfer window, and he believes Tottenham need to move quickly to sign their targets.

Pochettino has told Sky Sports that he feels Tottenham need to sign players in January before the likes of Manchester City, Manchester United, Liverpool and Chelsea pursue them in the summer, asn Spurs will struggle to compete with those clubs.

Pochettino noted that it's hard to find the right player in the January transfer window, but the 2015 deal to land Dele Alli from MK Dons is an example of how Spurs were quick out of the traps in order to sign such a talented player - and Spurs face 'losing' in the transfer market if they don't move quickly, as he wants.

“We need to sign players in January and bring them in six months before," Pochettino said. “If not, we're going to compete in the same period as [Manchester] City, [Manchester] United, Liverpool and Chelsea. We're going to struggle to bring in the players we want.”

“In January it's so difficult to find the right profile of the player to add in this transfer window to help you achieve what you want. Dele is a very good example that you need to anticipate and today we are at a club that needs to anticipate. We cannot be reactive because if we are, we are going to lose,” he added.
