He told The Times that Alli 'lost the plot', adding: "Dele Alli is a talented player but he should know when to take the sensible option rather than try his little flicks.
"This was not a night for a Harlem Globetrotters performance from the away side but rather a solid professional display."
Alli missed a second half chance when the ball fell to him from a corner, but to his credit he did manage to win the equalising penalty, which Harry Kane scored.
