Arsenal legend Thierry Henry still isn't convinced about the team's title prospects, despite victory at Manchester City.

Making his punditry debut on Sky Sports after signing a £4 million-a-year deal with the broadcaster, Henry cautioned that Arsenal are missing "a big piece".

Addressing the weaknesses in the side's defensive record he said: "They are missing a Patrick Vieira, a Gilberto Silva. I'm not attacking anyone but those guys would have done anything for us, to allow the front four to perform well."

"I think that Arsenal don't have that now. It's easy to have a go at [Per] Mertesacker but does he have the right protection? It is a team effort and I don't think they have that now. That position is one of, if not the most, important position on the pitch. You need to have protection."
