Liverpool legend Jamie Carragher says Arsene Wenger's lack of ruthlessness has hurt Arsenal.

Carragher feels the French boss must be questioned for the mentality of his squad.

He told the Daily Mail: "The board aren't the only ones with shortcomings.

"You have to question Wenger for the character of his squad.

"They are in a comfort zone, which stems from the fact Wenger lacks the ruthlessness of Sir Alex Ferguson and Jose Mourinho to send shockwaves through the dressing room.

"The profile of player he targets now is a mystery to me, considering the template of the team he had from 1998 to 2004; he used to buy players with power and pace to accompany technique but now it seems as if he favours technique over everything, from physical strength to character."
