See I disagree on the last bit. Im afraid I dont buy Tommy at LM. Would love to see hin prove me wrong as I love him. I dont think he will though.
Best player we have IMO.
I completely agree with Bairnardo's assessment though. He's an excellent WB at this level, just a passable LB and an, as yet, unknown wide left mid. WB is a different role to playing as a winger. The WB gets the chance to see the play unfold in front of him and therefore run in to space that he sees being created. A winger generally receives the ball then needs to start looking to beat people to create the space himself.
Robson does have the ability to beat a man though (and does regularly) so I would be happy enough with trying him at left mid to see what happens.
