Like it or not, Rooney will raise the profile of the club. Remember Moshiri's comments at the AGM about us having a small window in which to catch up to the top 6? Rooney's arrival will help towards achieving that aim, albeit not necessarily on the pitch. In terms of exposure and making the club more attractive to other players and neutral supporters, it is a no brainer. Also, his experience and winners mentality will be a bonus in and around the squad. I really can't see what harm it would do having him here for 2 seasons before moving into a coaching role with the club.
My concern is how is the 150k a week going to affect attracting other top talent and paying their wages?
How much can we afford?
If Rooney doesn't play well that's a heck of a lot of money to have tied up in a player that may or may not have that much more to give at the highest level.
And is Rooney going to be replacing Lukaku or playing with him?
I get why some people are positive about him coming back and he may still have a lot to give on the pitch, despite my own worries, but we still don't know how strong a financial position we're going to be in or how much Moshiri can invest.
If Rooney will be Lukaku's replacement and we're going to pay him 150k a week that's a big risk on a player who doesn't look after himself off the pitch. If it's not going to hamper our spending on other players then I'll have to put my trust in Koeman and the board knowing what they're doing but if Rooney is going to be the only significant player coming in this summer it's a big risk.
