I love it when people talk about Swansea City dating back to when they were a league 1 side, who have no idea about them.
Martinez took over at Swansea having formerly been a player there, he was still well respected by a lot of the dressing room and took over from Kenny Jackett, who didn't have the team playing particularly exciting stuff. Martinez kept the side functional, rather than eye catching for quite a few months before putting his style on things. He, having gone to Wigan, was replaced by Paulo Sousa, who was playing remarkably negative football. He added the defensive solidarity - Martinez was responsible for the quick passing, pass and move game. After Sousa was disappointing and left, Brendan Rodgers came in - not because he had this amazing reputation for great football, but because he came from Chelsea, he'd done very, very badly at both Reading and Watford. He added pressing - Barcelona style pressing to their game. A combination of Martinez, Sousa and Rodgers are responsible for Swansea's playing style, no individual, and certainly not their attention seeking Chairman, Huw Jenkins.
