Something tells me though Fletcher isn't just sitting on his butt.
A complete guess I know, but I reckon he's a pro that's kept himself pretty fit, maybe not match fit, but a few weeks would change that.
A lot of what Fletcher can give is in his brain, an intelligent player who can give assists as well as goals.
Georgie Gent, a young left-sided player, is set to join on loan from Blackburn. If so, he's the Furlong/Penney replacement we've all hoped for.

Shaw is 25, has had a preseason, has had some game time already this season, knows the league and has worked with the manager before. That adds up to a sensible signing. No guarantee it'll work out at Fir Park, but on paper makes sense..
