For 5 and 7 a side i'm great cause I like to think i'm quite well rounded, i'm decent in the air, strong, have a great shot, composed when one on one. My main weakness would be speed, but i've got a footballing brain and can outwit other players.
5 a side I like to play further back cause up front you very rarely have time on the ball, and I like started the play by spreading it to the wings, making a forward run and more often than not blasting it in to the back of the net.
Touch wood, I haven't suffered from too many injuries, 'only' broke my leg once in a 5 a side and slightly pulled my ankle ligaments twice in a 'career' that has been over 15 years
