Tottenham legend Ossie Ardiles has questioned whether Robbie Keane and Luka Modric can play in the same team.
Ardiles watched Spurs beat Liverpool 2-1 on Sunday and said: "Keane is a wonderful character to have around but is not really an out and out striker.
"Modric is crucial for Spurs' chances this year and he is most effective just behind the strikers."
