When most people refer to someone having'a winnning mentality' what they usually mean is that they spout loads of meaningless cliches or pump their fist and shout a lot.
When Hughes came in there were loads on here stating that this would see the end of stuff like bad results at Wigan because he was a hard task master/ a winner/ wouldn't stand for it/ creates a siege mentality/ blah, blah, blah.
Based not on anything tangible, only based on the fact that he talked a lot about 'winning mentalities', 'football factories', etc and had some sort of reputation of being kind of hard.
He wouldn't allow results like the relaxed Sven did. Then came WestBrom, Brighton, Forest, etc.
Not to mention that we hadrecent history of so-called 'winners' in the manager's seat and creating nothing like a team with a 'winning mentality' - Ball, Pearce, etc.
People have different styles, but talking the talk and being seen, and liking to be seen, as 'a winner' usually has feck all to do with it.
On the playing side. Bellamy is apparently a winner. Runs a lot, good on the pitch attitude, moans about everything, has a will to win, etc. So why is someone like Kuyt, a mild mannered bloke who has a meek personaility, more successful as a player and much more of 'a winner' if you compare careers?
Of course, I could pick better examples (choose him because he stayed at Liverpool whilst Bellamy was shipped out) and others could choose examples that show Bellamy as 'a winner'.
But the point remains that cliches, fist pumping, talking about a winning mentality and wanting to be seen as 'a winner' rarely have anything to do with creating success. Success can be moulded with a variety of styles, including disciplinarian and including relaxed, and it makes me want to knaw my arm off when people, despite the lessons of history, fall for all the 'winning mentality' rhetoric of chancers desperate to pander to their own ego.
(I remember hearing a Blackpool player, that thug from the centre of midfield (Bamber? Not sure, don't think it was. A fatish bloke who kicked people, can't remember the name) years ago on TV spouting off about how he was a winner and that is why they had got some important result. It made me wonder why such a 'winner' was therefore plying his trade as a journeyman with little success and scant reward compared to many other players. Harsh on him, maybe, but it summed up all this 'winner/winning mentality' rubbish for me
