Sports   (Talk about balls here.)

Young players slipping through the net happens quite often at all clubs. Frank Stapleton had trials at United in the mid 70s and he ended up coming back as a big money signing later.
Apparently Gary Mc Allister was a massive United fan and went down to be looked at as a youngster then came back to Old Trafford later with Leeds and Liverpool amongst others.
David Platt is a well known example who went on to become England captain.
Fergie wrote a lovely letter to Pique when he was leaving saying he would end up coming back one day and haunting him, did he!!!
Having said that I saw him in one game for United we were getting bombarded in the air and he couldn't seem to handle it, he then goes back to Barca were the ball is on the floor most of the time and he looked a world beater, (horses for courses I suppose).
