Fletcher needs more time on the pitch.
When he starts matches he's been able to show what he can do and has performed well in some very big games for United. His passing is very good once he finds his range and he adds a lot of energy and bite to the midfield.
I hope the days of him playing right midfield are over because he was always poor there and I don't think he's very effective when coming on for the last few minutes of a game. It always seems to take him a while to get into the flow of a game and if he's coming on late he tends to gives the ball away and loses out in tackles too often for my liking.
This isn't helped by his sporadic appearances. He'll start one game and then we won't see him for a month. I think if he played more consistently he'd be more effective generally and from the bench.
The question is, will he get the time on the pitch he needs to improve with the wealth of midfield talent we have at the club? Probably not imo, but I'd still hang onto him, for now at least, because he is a good squad player and, like I said, has performed well in some big games for us.
