I don't understand why people don't rate Welbeck - he's the perfect fit for Arsenal that's for sure. Players like Milner and Welbeck are crucial if you want to do well. They run all game, will play in any position and will always give everything. How many younger players would put up with having to play every position other than striker for so long. His goal scoring record for England proves he is capable even if he will never be particularly prolific. He might only score 1 in 3 or 4 shots whereas top strikers look at 1 in 2 but he will still look to get into those good positions. I guarantee when Sturridge is back fit, his combination with Rooney will have zero impact in comparison to Welbeck and Rooney. Welbeck is quick with the ball, holds onto it well and makes runs in behind the defence. He also tracks back (biggest skill there is) and defends with everything. You won't get that from Sturridge. Arsenal didn't get it from Giroud.
I hope he scores against the rags, and I hope he celebrates too. He's the sort of player City fans would love. If Dzeko scored half as many goals but worked twice as hard we'd love him more too!
