In the poem Disabled, How successfully does the writer compare the idea of sport and war? Using which techniques and phrases?

The speaker juxtaposes the masculine wounds of sport with the wounds of war. One time before the war he saw a blood smear on his leg and thought it looked like the "matches carried shoulder-high". He had been drinking after football and he thought he might as well sign up for war. Besides, someone had told him he would look like a god in kilts. This is why he joined the war, and it was also for Meg.
