We're going to have to make a big decision in regards to what we do with Rashford next season. I don't think he will start, but I still want him to get loads of games, in order for him to keep progressing.
Personally, I would move Rooney to number 10, keep Martial on the wing, and get in a first choice striker. People are calling for Lukaku, but at only 22, it will slow down the development of Rashford. Ideally, we should probably be looking at a striker around 27/28, so when he gets to about 30, we can slowly start to faze him out, hoping Rashford will be ready to be first choice at 21/22. Of course we'd still have Martial too.
