They're not the problem, the clueless play around the opposition box is. That's down to the 'creative players' like Mirallas, Osman, Barkley, Pienaar. Just not cute enough I'm afraid. Leaden footed and slow of wit.
Why are we playing 2 sitters against palace though? It didn't work and hasn't worked against teams who want to sit back and defend! We need a plan B and that formation hasn't changed all season.
