Louis van Gaal felt the introduction of Fernando Llorente was the difference after Tottenham's stunning Champions League win at Ajax.

Lucas Moura's hat-trick saw Spurs win 3-2 and into the final 3-3 on the away goals aggregate.

Former Ajax coach Van Gaal said, "The introduction of Fernando Llorente made the big difference after the break,.

"Matthijs de Ligt and Daley Blind were embarrassed by him, also by the connecting midfielders of the Spurs. The defence of Ajax could not play that.

"This defeat was completely unnecessary. At half time there was nothing wrong with a 2-0 lead. In the second half, Tottenham took more and more risk and more and more attackers entered the field. Ajax made the wrong choices in possession of the ball in that phase."
