Ivan Rakitic , Should Manchester United sign him in January?

Exactly the player that we need.The only problem is we will have Chelsea to compete with if we are going to sign him and thats not a good thing.When ever we have gone against big money clubs in transfer market we have failed (Except when we signed RVP). Remember Lucas Moura,Eden Hazard,Juan Mata,. The 25 year old is said to be frustrated at Sevilla. How much do you think is he worth?
