So, according to The Scotsman, apparently John Sutton scored for Motherwell against Thistle yesterday.

There have been a few mentions that we might be interested, we're certainly short in centre midfield at the moment. Having taken a quick look at RangersMedia for some LOLZ it'd seem that the opposite of what you're suggesting is true; their issue seems to be he was anonymous in the seaside leagues and an imposter under Sally but has come on to a game and has been one of their better players under Warburton.
The coverage of this has been amazing; CNN, GQ even Time have covered it. On top of that some of the memes have been absolute gold. Genuinely one of the most entertaining stories I've read in ages. Nicely done Thistle.
