Your tactic seems to be a solid counter to him. With his 2-1-5-1-1 and a focus on left side you could set your right side defenders with arrows to make sure they focus on defence. Long passing can negate his midfield but depending on your players so can short passes due to increased possession. His weakness is definatly his flanks so start off playing long passes and see if you get the desired result. If not switch down to balanced or short and see if you get the desired result. I dont know the speed or quality of his defenders compared to your striker so many unknown factors..
