We shouldn't accept the length, but I don't think the wages are THAT crazy are some are pointing out... he would be on level with Martial and Rash, wouldn't he? He has a tone of experience at top level, including lots of CL and with the national team. You have to pay for that kind of thing.
He is super profesional and hard working, and yeah, he surely plays for money, is his job, he is a fan of a club in Uruguay, so?
He wouldn't be just a backup, he would provide competition, something Ighalo can't do.
We shouldn't pay a lot on fees though, of course, that and contract length is why I don't think it will happen and rightly so in that context.
By the way, I have had him in football manager for a while, works well with Sancho on the right... that means it is happening isn't it? (no Telles though...)
