Bruce. At the moment.
Better balance in the team, used the flanks better, more fighting spirit, less prone to collapse like a pack of cards, more adaptable against different sorts of teams in style of play than Martinez’s side.
Martinez should do some serious thinking about why he can get some good results against better sides, and not against the rest. To me its because he plays too narrow against lesser teams with his winger policy, making us easy to defend against
But he’s learning, and may become a better manager than Bruce.
