Hate to be the one that breaks it to him.. But the only major trophy Atletico will win in the coming years is the Europa League trophy if they get knocked out of CL.
Can't even see them beat Real in the worth-nothing supercup. They will always choke in finals, new players won't change that. And I don't see them securing a league-title, when Real will press all the can to get it in the next 2-3 years, and us being a better league team than them overall.
If he comes here he is guaranteed trophies, in Atletico they are a happy coincidence, tbh.
