Harry Redknapp has managed more games of football than you've had cooked breakfasts. And he's probably had more of those than you too (see evidence above).
So with that vast experience to draw on, we spoke to Harry to see if he could offer us some management tips: specifically, how to deal with people who care about money more than success, how to deal with disruptive influences, and how to stop egos from spiralling out of control.

Pep's reportedly getting rid of bad apples at Man City. Did you ever do that?
Does players earning more than managers make it more difficult to control them?
Have you ever employed a spy - a trusted player to let you know what's going on?
What's your tactic if you can't get rid of them - if they've got another year of their contract and no one else wants them?
A famous example was when you managed Adel Taraabt at QPR - do you still think you did the right thing when you called him out publicly? Do you stand by that?
"Yeah, absolutely. Getting £70,000 a week to play football. When you're a footballer, you have to get fit and live like a footballer and train properly and turn up on time. You have to be fit enough to play, you have to do a preseason to get fit. Listen, I'm not the only one - he's gone to Benfica and hasn't played one game. It's not only me, it was other people before me had the same... I didn't let him go in the end, Chris Ramsay let him go, he took over - Les Ferdinand saw the problems when he was there. It's a shame because he has got talent, he's got great creative skill, good ability but at the end of the day he's probably played about 10 games in the last six years."
Alex Ferguson never criticised a player in public no matter how bad they'd done - why do you think he was able to get away with that tactic?
Paul Pogba's just joined Manchester United - world record transfer fee, he's only 23 - how on earth do you control the ego of someone like that? How would you go about doing that?
How would you deal these days with social media and stuff like that - do you allow the players a bit of freedom, or none at all?
As well as players with lots of money, there's the rise of the mega-rich chairman (eg. Sheikh Mansour) with astonishing wealth, even lower down the league. As a manager, how do you deal with a difficult chairman like that, who perhaps doesn't understand the game, wants to throw money at anything? Are you confrontational, or do you go softly-softly?
