Mauricio Pochettino stated that he wouldn't be upset if Spurs failed to upgrade their squad over the winter transfer window. He cited the difficulty for a player to integrate within a new side in a short period of time.

Although already at the maximum for foreign players permitted on a Champions League squad, Pochettino would prefer to sign English players if Tottenham do upgrade. 

Pochettino said “I know very well that January is always difficult and look what happened to different players that arrived last January. It takes time to understand and perform, to fit with the team".
