Manchester City have confirmed the signing of Jack Rodwell on a five-year deal.

It surfaced as a shock deal before the Community Shield game on Sunday kicked off, and judging by City's performance and shape he's a great addition.

Fits the shape

Roberto Mancini has switched to a 3-5-2 formation. It uses three central defenders and two flying full-backs and it's something he's toyed with during preseason.

City look weakest in central defence and there were concerns heading into the new season about the depth available to Mancini in this position.

Adding a third centre-back certainly increased concern, but Rodwell arriving means he can play in the back line or switch to defensive midfield mid-game.

Value for money

Out of the options available to Mancini for this mould of player, Rodwell is the most reasonably priced and the least expensive.

Javi Martinez, valued at around €40 million, was the long-term target but Athletic Bilbao won't budge. Daniele De Rossi would cost around the same but has no re-sale value.

Rodwell is only 21-years-old. His upside is huge and can exceed Martinez's ability should be steer clear of injuries. 

Eases home-grown issues

He's English, so it always helps with the UEFA Champions League ruling if your new signing can be considered home-grown.

City aren't facing issues in that respect, but with Owen Hargreaves gone and Adam Johnson potentially going, it's important to grab another quality English player.
