You can stick with one manager and have no wins, no trophies, or you can have so many different managers and win a lot. It comes down to the players, to the desire, and the way the club likes to behave.
Clubs don't change managers unless there is something wrong.
The Porto players were with me for two and a half years, they believed in me, in my methods, in the way we do it. The next day I go and a manager arrives who works completely differently.
I've always felt happy at Newcastle. But things have gone a bit differently for me since we got a new manager.
You always have years when you go through transition and the side needs to be rebuilt. Or you have changes in terms of managers.
It's not easy when you have a new manager because you have to try and adapt yourself to him, the team, training sessions, and the game.
I knew that Chelsea was a club that changed its manager reasonably often.
Obviously it's very hard to leave a club that you've supported all your life. But the reason that I've come to Birmingham is that I think Steve Bruce is one of the best young managers in the country and that Birmingham as a club is a sleeping giant.
Newcastle was tough - the manager who'd signed me, Bobby Robson, got sacked three games into the season, so a new manager arrived, and I ended up going on loan again, to Aston Villa.
If the team start picking up results, everything will look more positive and people will forget about the previous manager, as long as we're successful on the pitch.
I am interested in how much and how quickly Klopp, the manager that I know, can change the team at Liverpool.
I've been in football a long time now and I've seen plenty of managers and players come and go. It is part and parcel of the game.
When you change a manager like Sir Alex Ferguson, it is difficult.
I went through 15 years as a coach at Spurs working under seven, eight different managers. And every time a manager went, you weren't sure whether you'd still be there. Some people might worry about these things but I never have.
I've seen 18 managers go at the clubs I've been playing for. It's a part of football, isn't it?
Luckily for me, Hereford restarted their youth team. I trained a few times with the first team before my first stroke of luck, when the club's youth team coach Pete Beadle, someone who knew me well, became the first-team manager.
I have played for many clubs, and for many managers, and been through many highs and lows. But one thing has never changed. And that's the feeling of scoring a goal.
