I dont know if this guy worth this type of money but we are desperate for a left back (or two) so Txiki is just gonna pay what they tell him.
Looking at other fullback transfers, huge talent from Atletico to Real Theo Hernandez leftback, around 30m €, I think his name was mentioned with City as well eariler, than Dani Alves to PSG for free, also Yuri Berchiche from Sociedad to PSG for around 15m€, then Kolasinac who was on City's radar to Arsenal as a free transfer.
We fucked up this a bit imo, we should have got Kolasinac+Alves early on in the window than fight for Mendy+Waler later on and from 100m pounds we would have got 4 good full backs imo. Kolasinac good enough imo as a LB to rotate with Mendy.
Now we still paying the 100m or more for Mendy+Walker, and looking to spend another 60m Danilo+Bertrand maybe. And we probably kill the way to promote Angelino/Maffeo in next two years.
We made a fucking mess to let these positions to rot so much until we have very old and very slow players in these positions getting their contract ended so not even income from letting them go maybe 2-3m for Kolarov...
Same thing can hapen in the middle of the park if we dont start to solve it now. Delph, Fernando, Yaya, Fernandinho, Gundogan, first two could be leaving, Yaya leaving next summer, Fernandinho too probably as no new contract for him, so we need to get fresh, strong midfielder in right now imo.
