Rooney wouldn't start all 55/60 games of the season. And lukaku will still get lots of minutes in sub appearances on top of the 15 starts he would probably get. And last season with west brom he wasn't a starter very often. And he is still young so its not like being second choice would negatively impact him. But as i have said imo, if we get Rooney then great as we have a lot options, a great striker and someone who is very versatile. And if not well then Lukaku gets his big chance, and Torres will have to get his shit together to challenge for first spot.
