Graeme Souness says Harry Kane should consider leaving Tottenham if Jose Mourinho's side fail to beat Manchester City in the Carabao Cup or make top four this season.
Souness believes Kane's 'individual efforts have been world class' and claims Tottenham are running out of 'time to deliver collectively on what his contribution deserves'.
The Sky Sports pundit believes the England striker would ‘walk into’ the Real Madrid or Barcelona team but warns the 'window of opportunity to do so while in his prime is not big'.
Having scored 214 goals in 324 appearances for Spurs, Souness says Kane should consider 'calling his agent' if Tottenham fail to pick up any silverware this season as his individual efforts deserve more.
