Just had a check as well (not on a free) seems he is one of these part owned players and Lazio had to pay an extra €14mil to some holding company or whatever, seems a bit iffy to me although that was 2 years ago. He was on €7mil a year wages as well works out about £6mil or £115K a week, not for a few years yet will we be paying that sort of money. Granted this was on Wikilietoye.
Apparently he offered to take a pay cut last year. http://forzaitalianfootball.com/2012/07/zarate-offers-to-take-pay-cut-to-stay-at-lazio/ Hope he doesn't mind taking a pay cut for us.
Not sure mate not a big fan of all that part ownership malarkey seems like you will have two lots of agents etc. to pay.
That's a deal worth doing for Arsenal! Two quality players and **** loads of cash for a lad they paid five million for. Yes he's hard to replace but with those two in the side and all that money to spend on a winger they'd surely break into the top four again.
