MTL_Barca, OK we can get away from the semantics, total waste, big disappointment, somewhat disappointing, etc. I don't think it will be as bad as Alexis Sanchez to MU or Arda Turan to Barca (as IMO it was all money with absolutely zero product and a locker room problem), but I leave that.
Not that he isn't a quality player but more like that i don't believe anybody would say "yeah i'm super happy we bought him for 160M" some months into the new season. I just can't see that happening with the way we build the squad atm.
He isn't a bad player, but for what he offered this far we payed like 100 mil too much and his salary is way too high. He was supposed to immediately strengthen our team and replace Iniesta. "Proven world class" in his prime age wise but he is far away from the expectations.
Also it's not like there are only 2 options. Coutinho could for example play better and still not play like a 160M signing. In that case i would say yeah ok we overpaid a bit, not easy getting a Liverpool starter and we had all the Neymar money so who cares. But imo this season was just too disappointing to phrase it like that.
Only major factor to change the situation would be getting a new coach next season. Not necessarily because i think Valverde is responsible for Coutinhos bad showings but because it could really shake up the squad, with Valverde and his established system, established player roles etc i see no way Coutinhos situation can drastically change.
So if it continues like this and there is a decent offer i would sell him and just admit the transfer wasn't good.
All fair points and I mostly agree with some minor tweaks.
Coutinho is an attacking midfielder more than a winger. There is a chance he and Valverde or another manager comes to realize if he wants to be a regular starter with a team with Messi he is going to have to play more like a midfielder and grow in some aspects of his game. He was frequently in an advanced central midfield position at Liverpool (and Klopp did not want him to go and they are still seeking a replacement, almost sprung for Fekir this summer) and we have seen a little bit of it this year, though I think clearly Valverde this year will at most sprinkle it in. There is a summer offseason to work on this, and now maybe it is pretty clear Dembele looks like a fixture PC can focus on training into another role.
The other part is I don't think over Coutinho's 15 months at Barca he has been nearly as bad as you do. I think he was only truly bad some of the 1st part 18-19 through maybe January. He was outstanding in La Liga season (2nd best player once he joined in league) and been OK Feb and on--maybe not great numbers but linking up well with Suarez and Messi. I think one of the challenges with him is you see so much difference with Dembele in the team vs not, and we usually contrast that with Coutinho v Dembele. In truth Dembele makes all our other alternatives look slow and non-explosive. And could having a speedier CF like Jovic as an alternative to Suarez here and there make a line Coutinho works well in? Perhaps. Part of the issue is the combined workrate/pace of Suarez, Messi & Coutinho doesn't cut it.
So I am not as pessimistic about the transfer as you are. Yeah we overpayed, but we got fantastic deals on Arthur and Lenglet, and looking good for Dembele and Malcom. It comes with the territory of some buys being great, some good, average, some of poor value, and yes sometimes terrible. I am totally fine if we sell for 100+ and take some loss on this move when you consider all the moves the last few years. It is a move like Arda (when he said he wanted to move from AtM to Barca so he doesn't have to work as much) that I just don't understand and shake my head. (or going back to Vermaelen, Alex Song, etc)
