He told BetIdeas.com: "The PFA is not the main problem. The main problem is bigger than that. Your main problem is if you treat two players like that and the rest of the team sees it, which they will, because it's their mates - and I know players can be selfish and are selfish and have to be selfish - they all know that's what I'm going to get. Now, management doesn't always think along these terms because it's short term. There's a big danger there. And it is a warning. Being on just about every side of the game and seeing it, it can damage spirit. Players are selfish and they take care of themselves. But Raheem Sterling is liked, he's popular within that dressing room. You certainly don't just blank your mates. So Chelsea need to be careful because in the end if they have got these players that are in six, seven, eight year contracts. Nicholas Jackson was the main man. He's great. And then suddenly he's in the bomb squad. And then he's not, ‘We want you back in’. So be careful because everybody now knows that's what happens. I promise you that's dangerous. When you treat workers like that, the other workers know this. Just be careful."
