Stoke City's substitutes have struggled to make an impact in their opening matches, leaving manager Mark Robins questioning their attitude and motivation. The Potters have rebuilt their medical department and changed how they work between games to try and avoid the number of injuries that ruined last season, but right now, they look a bit undercooked. That means they need their substitutes to make an impact off the bench, but the manager was left questioning the attitude and motivation of the players he brought on after the game. In both of their opening matches, opposition substitutes have been decisive, while Stoke's have struggled to affect the action. Ben Johnson looks like a good addition to the squad, and George Hirst got valuable minutes under his belt as both made their debuts. Stoke need a positive result pretty quickly though, to restore the optimism created by a summer of significant expenditure in the transfer market.
