Living in Swansea, I all I can say is everything they have acheived all started from Martinez.
The style of football, the determination and not going out of their means to try and get success.
He likes to build a solid defence (ok problem with that at Wigan), two midfielders that go and get the ball off the defence to start any forward movement, another cm to link up and find gaps to play in. Then two wingers to join in and provide a threat and the striker to stay in front of goal (DB).
If the fans can understand the keep ball philosophy then it can be very enjoyable and very effective. But a lot of fans get annoyed with not going forward quickly.
I think he could be good for us.
