Tottenham midfielder Moussa Sissoko is out of their Champions League semifinal first-leg against Ajax.

The midfielder, who is a candidate for the club's player of the season, suffered a groin injury in the quarter-final second-leg match at Manchester City and has been ruled out by boss Mauricio Pochettino for two weeks.

"Moussa Sissoko is not going to be fit, maybe for the next two weeks, we hope he can recover before but I am not so optimistic," Pochettino said.

"Harry Winks we don't know because it is a problem that is one day very good, next day not very good, it is about assessing each day.

"We hope he will be available for Tuesday but we are not sure."
