Generally Martinez is happier to rotate his squad more than Moyes. I suspect that Browning will get some game time at right back, and Galloway will get some game time at left back. Pennington is a real bonus as I don't think we expected him to get this far. He will look to loan one of them out. Possibly Jagielka will be fazed out over the next 2-3 years as might Baines.
Do you think Galloway is further up the pecking order than Garbutt? I always thought Garbutt was frozen out of the last few games due mainly to his contract situation than his ability. With Oviedo also seemingly available at left back, that's a really competitive area.
