No success anywhere, but was a massive factor in enabling Swansea to climb the FL to the Prem. Won the FA Cup with a distinctly average Wigan team.
The football under Martinez was some of the best i've ever watched as a blue. Even in his last season with us, we were in the two domestic cup semi-finals and could have conceivably won both (especially v United).
Obviously he was far from the finished article as a young manager, but we had a clear style of play and looked like we could actually win a trophy, despite our league form suffering as we finished mid-table twice. It looked like there was a plan in place for the future. Brought Stones and Barkley in to the first team, attracted Lukaku, Deulofeu. We'll never know now.
Belgium also appointed him to work with their 'golden generation' of players for the World Cup. 100% fraud though.
