Dave Whelan (Wigan chairman) has always said that he would never stand in his way. He was actually prepared to let him leave last season if that was what Martinez wanted.
I note what you say, but the end of this season has a different twist to the previous season at Wigan Athletic. Dave Whelan is a shrewd businessman and is aware of the financial value of being a Premiership club. There is the other matter connecting Roberto Martinez to Wigan Athletic which is his playing days there as one of the "Three Amigos" quite some time ago.
This is why I used Owen Coyle with his time at both Burnley and at Bolton Wanderers as a comparison with Roberto Martinez, in terms of whose motivational skills were the better of these two managers.
Undoubtedly, Roberto Martinez, with another season of football management *under his belt" in terms of managerial experience, will most certainly be the target of many clubs seeking " a new hand on the rudder", so to speak. However, whilst this will will be to the benefit of another club, how do you feel the club and supporters of Wigan Athletic will view matters? All I can say is that if your own club were in such a situation, where an escape from relegation against against all the odds (noting the type and calibre of teams that faced Wigan Athletic in their last nine league matches) was achieved, after your euphoria had subsided, how would you personally view the possible loss of your manager, if he was the same calibre as Roberto Martinez is ?
We all know that matters have to...and actually do...move onwards. All I want to show how the matter will be viewed by the expressed feelings of supporters of the club actually losing such a manager.
