Paul Merson has identified left back as Manchester City’s weakness, and thinks Theo Walcott could exploit it.

City have been frightening form this season, but have been winning games lately with a make-shift left back.

After Benjamin Mendy injured his cruciate ligaments, Pep Guardiola has been relying upon Fabian Delph in the position. In fairness to the former Villa man, he’s been doing pretty well.

Merson, though, believes he could be a weak link for City when they came up against Arsenal, and knows just the player who could exploit it.

“I like what Pep Guardiola has done in bringing in Kyle Walker. Going forward he’s among the best in the world in that position,” Merson said, as reported by the Daily Star.

“The left-back position is the one concern with Fabian Delph going in there, but nobody has a go at them.

“I would play Theo Walcott on the right when Arsenal visit Manchester City on Sunday and have a right go at that area, because that’s their Achilles heel.”

It’s not the most unreasonable suggestion that Merson has ever made.

Walcott does have the pace that could trouble a make-shift defender, while his goalscoring record against City is good.

However, Walcott has been out of favour at the club for a few months now, and only gets games in the cup competitions.

With no real form behind him, it’d be a bit much to throw him into such a difficult game.

Either Mesut Ozil or Alex Iwobi is expected to play on the right hand side for Arsenal.

Left back could be a weakness for City, but the reason why teams haven’t ‘got at it’ is simply because they haven’t been able to.
