Arsenal hero Emmanuel Petit says manager Mikel Arteta hasn't utilised his squad more.
The Gunners have dropped four points from the last two games to allow Manchester City back in the title race.
Petit told Legal Sportsbooks: Recently yes [Arteta hasn't rotated enough]. I think it was the same against Liverpool.
He took some time to make subs and some players should have been involved earlier.
The likes of Trossard, who has been brilliant since he joined. Arteta has his first XI in mind and wats to stay with them because he thinks they have been unbelievable since the beginning.
He's probably thinking 'why should I change them?' Because they were winning game after game?
I can understand but in the meantime, as he's such a young manager, maybe he has to learn as well from that."
