Arsenal legend Emmanuel Petit says celebrations over their second-half of the season should be tempered.

The Gunners will again finish the campaign trophyless.

"Arsenal received huge criticism after the AC Milan disappointment," said Petit.

"This affected the belief and ego of the players, which is why they came back with such a big hunger to show to everyone they were wrong.

"The performances since then have been magnificent.

"But I am disappointed as well. Why did they have to wait for the criticism to show people what they can do? I am quite frustrated because it proved they can do more."
