Former Manchester United scout Patrik Andersson has questioned whether AZ Alkmaar midfielder Rasmus Elm would be good enough for Old Trafford.
Elm has been linked with United again this week.
But Andersson told fotbollskanalen.se: "It depends on what position you are seeking. If you see him as the inner midfielder or winger. The only thing I know that you look at in terms winger is that players would be the fastest on the team .
"We're talking of course about one of the biggest clubs and after that we are looking at would he be better than what you had or have the potential to become one. After all, sure, now that Rasmus has been injury-free for quite a while, but we're talking the Dutch league and he will certainly need to take steps in his development."
