I've said before that if it's a bargain price I'd take him but anything excessive I'd rather invest in other areas.
As others, mostly Theon, have said, we don't just have Rooney, Welbeck and Hernandez, we also have Kagawa not too. His natural position is one which entails needing only 1 striker in the team. Additionally his style of play complements each of those 3 strikers very well and in some ways could be the player to bring the best out of them, for example I think Hernandez could thrive off him. If you say Kagawa could play in cm, then what happens to clev/ando/powell who all need games there not to mention scholes and giggs. If we go 433, then you're looking at using only 1 off Nani, Valencia and Young on a regular basis, the former 2 are to good for that.
Last year we didn't struggle for goals. Rooney getting approx 34 in all competitions is obviously considerably more than the other strikers but I don't think it was excessive. You expect the top striker in a top team to be in an around that number especially when they're the penalty taker. Most would say Hernandez had a poor second season and has shown he can do better and Welbeck will have learnt from his experience this year and in the summer. You would expect those two to get a better return.
Berba hardly featured last season, as I said Kagawa is effectively the fourth striker now and he had a good record at Dortmund, he will be good for goals. Not to mention in Nani, Valencia, and Young, if they stay fit thats 3 wingers who can all pitch in well. You can argue we'd have problems if Rooney gets injured but that's the same of any team. Personally whilst I accept it will be tougher if he did get inured I think we have the personel to cover for him, maybe not one player individually but there are a lot of players who can share the burden, particularly if we get better luck with injuries at the back.
Fitting in RVP will be tough too. You can talk about rotation all you want but RVP and Rooney are world class strikers, if they're fit, they play. You'd expect around 50 games each from them, maybe less from RVP given his history. That doesn't leave many games for Welbeck and Hernandez, especially with Kagawa around who is an established quality player. Coming off the back of the season Welbeck had and a good Euro's imo for him this is where he should be looking to push on. Adding Kagawa to the squad is one thing, adding him and RVP will seriously harm his chances not to mention hernandez.
And for me as much as I like RVP as I said we didn't really struggle for goals. We had big defensive issues that cost us. Not to mention I think one of the main areas we should be looking to improve is the link between the attack and midfield. It's something I think we've missed and although Rooney and RVP are capable of it, both imo are showing much more impact higher up the pitch and both seemed to have changed now to becoming more of the lead striker than the deeper striker. I know Rooney started off a little deeper last season but ultimately I think he played pretty high and doesn't look as good in the deeper role as he did.
Like I said at a bargain rate then I'd take him, he's top class. But for a relatively large fee I'd rather we put the money towards someone else. Having said that having lost out on Hazard and Lucas I'd expect Fergie to really want this, both because of his class and as a statement.
