Of course it is. You are 4 months from getting him for his wages and are paying a decent transfer fee, signing fee and agent fee. That's not being driven by anyone being burned as you claim but by United having to stump up ridiculous extras because they know they wouldn't get him in June. If anyone in charge at the club thought otherwise they wouldn't be doing it. 300k+ (the lower end of what is claimed) is what you would pay 29 year old Sanchez if you nailed him a on free. The Pogbas and co would accept this but you can bet agents are rubbing their hands together now to have their earner banging on the door if the rumoured extras end up getting confirmed. Then you have the impact this will have on future signings when a player who isn't even in the current top 10-15 in the EPL is getting 300k+ per week.
It's a terrible terrible deal for a 29 year old. Yeah it's not your money and the club can afford it but it doesn't make it any less retarded. It's incredibly short sighted with the knock on this will have, it has Joses mark all over it. Someone, somehow has managed to hold you to randsom for Sanchez and I just don't understand why other than he wouldn't entertain coming without it being so over the top.
Say City were buying him for 10% less overall cost, would you say the same?
I think the big difference of opinion is how highly he's rated, I'd have him among the best players in the EPL yet you've got him down as 10-15th? Hazard is probably the only player I'd have ahead of him in that position.
This is the way football is going, everyone is going to have to overpay to get a 'top' player. Wages, transfer fees, bonuses etc. PSG, Man City and Real Madrid will all be in for the top players too and if you think agents aren't going to try and shaft everyone, you are dead wrong.
