Former Gunners playmaker believes the current trequartista has been off-form for four months and his layoff could be beneficial to Arsene Wenger.
Arsenal have an exceptional record against Hull City.
Because of the club's form this season - where they have banked just ten points from seven matches and are eighth in the division - former star midfielder Paul Merson implies it is imperative that Arsenal continue that streak on Saturday.
"Arsenal have only won two Premier League games all season and that ain’t good enough," said Merson on his Sky Sports column.
"For that reason I think this is a must-win game against a Hull side that had a good result before the internationals and probably didn’t want a two-week break.
"You always want to play again when you’ve won. I have to go for Arsenal to win, but I think it will be a hard game for them."
Arsenal are currently hampered by a number of injuries to key personnel - most of them muscular - with Laurent Koscielny, Aaron Ramsey, Yaya Sanogo, Mathieu Debuchy and Olivier Giroud all occupying the physio room.
German international Mesut Ozil recently joined them due to a knee ligament problem, but Merson believes that, because of his substandard form this year, it could be a blessing in disguise.
"I do think the injury to Mesut Ozil might actually help the team," he said.
"I don’t think he’s been playing well and any other player would have been dropped if they’d played like he has over the last four months.
"He’s probably been playing unfit so it could be a blessing to give him a rest – and it gives the manager an easy decision to make."
