What about Bobby Kerr ? nobody was smaller or skinnier than him ( he's changed a bit now like ) but he was a great player, defenders couldn't get near him and Norman Hunter had to break his leg to stop him, I'll never forget the incident , you could hear the break all around Roker Park.
If MON plays 4-5-1 there is no point in playing Noble. Noble is best suited to a 4-4-2 formation, and playing alongside a big lad like Wickham.
