Mauricio Pochettino has admitted Tottenham cannot force Harry Kane to stay at the club.
Kane has always maintained he is happy at Spurs but Pochettino says Philippe Coutinho's move from Liverpool to Barcelona shows there can be no room for complacency.
Tottenham's star striker underlined his value again on Sunday by scoring twice in a 3-0 win over AFC Wimbledon as Pochettino's side eased into the FA Cup fourth round.
Jan Vertonghen's first club goal since October 2013, a sensational 30-yard strike, added some gloss late on at Wembley.
