Long-serving midfielder Paul Scharner believes Wigan are beginning to progress under manager Roberto Martinez.[LNB]The Spaniard arrived in the summer as successor to Steve Bruce after serving his apprenticeship with Swansea.[LNB]He was warmly welcomed back to the DW Stadium after wearing the colours of the club as a player when they were in the old fourth division. However, Wigan's stuttering start to the season led to questions about his ability to succeed at the highest level.[LNB]Now though Martinez could have the freedom of the town and beyond after a superb 3-1 victory against previously unbeaten Chelsea.[LNB]And Scharner said: "I have played against the top four about 30 times and never enjoyed a victory. So I am very pleased, especially for the supporters, as everyone was at the top of their game. We deserved to win.[LNB]"It is always difficult when you bring in a new manager and the philosophy changes 180 degrees from modern kick and rush to keeping possession. Things don't happen overnight."
