Azpi is on £180K a week or something along those lines. He will still have one year left on his contract in the summer but I'm guessing the club will agree to give him a free transfer at the end of the current season and he'll go. He's still a somewhat solid defender at the back but doesn't offer anything going forward these days, and even in his prime the attacking part of the game was never one of his strengths. Wonderful servant to the club for more than a decade but it's time to move on.
Rumor has it we've agreed personal terms with Gusto on a 6,5 year deal and he'd definitely be on way less money than Azpi going by the fact our latest permanent first team signings (Mudryk, Badiashile) are on under £100K/wk.
Haven't seen any reports on how much the other new lad Madueke is getting but less than Mudryk would be my best guess given how sought after and expensive Mudryk was. Whatever he's earning I'd assume Gusto would get around the same as Madueke seeing as they're of similar age, with similar experience and similar transfer values. Most reports put Madueke at €15K/wk at PSV and Gusto currently at €8K/wk at Lyon so maybe somewhere around £50-70K/wk wages for them?
Annual cost with Azpi is £9M in salary and for Gusto with amortisation + wages the total cost would be around the same or less than that. At most it would be a £35M fee and £70K/wk which on a 6,5 year deal would amount to £9M overall yearly cost so same as Azpi. If we get Gusto the final transfer fee and salary could both end up being less than those figures but I very much doubt either would be more. Replacing Azpi with Gusto would be a shrewd move by the club IMO.
