Not really. Just like he is not really responsible for the lack of goals.
Its a team sport. About 30 players in the squad, bunch of coaches working with the first team players, bunch of people working to ensure that the players and staff are able to focus on their jobs and have a good work environment. Team wins, team loses, team scores, team concedes.
Stop being so ****ing sensible. It's getting on my tits.
