"Before anything else, Barcelona should make a formal offer. Then we can sit down and speak."- Dennis Lachter, offering Arshavin up for transferDennis Lachter is the best football agent in the world. He's unscrupulous, devious, bold, greedy, and persistent. And if that's not enough, he's just shown that he's completely dedicated to providing the best deals for his players - even if he's no longer working for them.Arshavin and Lachter parted ways a couple of weeks ago, and yet Lachter's still trying to angle a move to Barcelona. I'm not sure why. There's no commission in it for him. My only guess is that Lachter is such a devoted agent that he's willing to pull for his player, without pay.How many football agents in the world would do that?I'm saying we should sign Lachter and give him responsibility for transfer negotiations. We need to turn his talents to good, instead of evil. If he was an Arsenal agent, our current negotiations with Fiorentina wouldn't be at an impasse - Melo would be ours, Eboue and Senderos would be out, and we'd probably even make a profit out of it. That's how highly I rate the guy.As it stands, it seems that Wenger's really keen on Melo but he can't afford to pay £21.5 million. Instead, he's offering two players, plus cash. It makes you wonder how much transfer money we've really got left. Could it be that the purchase of Vermaelen wiped us out? Are we relying on the sale of Adebayor to fund additional purchases? Are we going to miss out on a DM if we can't move a few players on?It's for reasons like these that I urge the Arse to sign Dennis Lachter.
