Manchester City boss Sven Goran Eriksson has described the transfer market as "a jungle".
"It is absolutely a jungle out there," he said. "I had no idea. I thought I would never be surprised, but I still don't knows how many agents are selling football players or how many agents are representing the same player. It is absolutely amazing. In one day you can have three different agents quoting three different prices for the same player. This has actually happened. You just have to laugh sometimes.
"The other day I was sitting with my coaches and my phone rang. It was an agent offering a player, so straight away I asked the price. You have to do that because I can't just phone the club and say I want this one. Ten minutes later another agent rang about the same player. I asked the price and it was three times higher than the first one. I have some experience of dealing with agents from my time at Lazio, but things have certainly moved on since then."
