Well we have to see how the game is going before deciding substitutions...scoreline, fitness, injuries and tactics are all things to be considered. Gabby will probably play the full 90 minutes as we may well need an out ball through the channels if we start to invite pressure in the second half...he's still a better option than Gestede and Ayew. If one of the midfield is struggling then I'd like to think he's learned his lesson and bring on Veretout, Richardson or Clark.
