Sunderland boss Martin O'Neill paid tribute to Arsene Wenger after dumping Arsenal out of the FA Cup.
Wenger found an ally in O'Neill, who does not believe the Frenchman deserves the criticism that is being aimed at him.
"We haven't always seen eye to eye but I think he's been fantastic for the English game," said O'Neill.
"Of course he'll be disappointed at the week, particularly losing the game in Milan.
"My own view is I don't think the criticism, which we all receive, is particularly merited. I think he's been one of the great managers and will be considered so."
