Kane damaged ligaments in his right ankle before the global break and Spurs originally said he would return in April.
The striker damaged lateral ligaments in his right ankle at Bournemouth on 11 March and the original expectation was that he would be out until mid-April. We need to assess him in the next few days. He's very positive and he is doing very well. "Every day he is improving", Pochettino said. Tottenham manager Mauricio Pochettino says "I can not say no, but I can not say yes" about Kane's availability for the match at Stamford Bridge.
'I can not say no, but I can not say yes. He is doing fantastic. "We are so pleased because after Bournemouth everyone thought it would be a long time, but that is not the case".
Pochettino, who ranks Spurs' rivalry with Chelsea on a par with Arsenal, does not think it is a winner-takes-all game.
But they confirmed on Thursday that Kane had "stepped up his rehabilitation" and Pochettino said at a news conference that he will be given every chance of being fit.More news: Heavy rain and storms by Thursday

Any game against Chelsea is a huge tie for Tottenham, yet Sunday's game carries huge importance for both sides.
While there was no guarantee that the Chelsea league fixture will see Kane return, Pochettino revealed that it is an eventuality and may happen next week if not this one. When you play this type of game there is pressure on both teams.
"Of course, [it's] always not only advice, [it] is talk [aimed at] trying to help the players, to help the players when they need to be pushed". But for us, three points for us will be fantastic'.
"They are a very good team, and always it is tough to compete with them", he said.
"I think it is not a point of focus for us".
"There is still a lot of games to play, but always it's important for your confidence, motivation to win on Chelsea would be fantastic", he added.
