Chelsea boss Mauricio Pochettino admitted he could not guarantee that his club captain Conor Gallagher would still be at the club by the end of the window.
Gallagher has become a key player for the Blues under the Argentine this season - starting 19 times and providing four assists - but the Chelsea youth prospect has emerged as one of few players who could depart Stamford Bridge this month.
Mail Sport's Sami Mokbel reported this week that Tottenham were a shock team Gallagher could join, saying the deal 'has got legs' after Spurs were linked with the player last summer.
