Tottenham midfielder Moussa Sissoko has failed to live up to expectations following his £30m move from Newcastle, says manager Mauricio Pochettino.
France international Sissoko, 27. did not even make the bench for Spurs' 2-1 defeat at Chelsea on Saturday.
"Football is not about money," said Pochettino.
"You need to show on the training ground you are better than another team-mate and you deserve to be involved."
Sissoko joined Spurs on a five-year contract after they matched Everton's bid on transfer deadline day in September.
He has made five starts in all competitions, plus five more appearances as a substitute.
