Coutinho will stay this season and probably leave next summer. Every news source points out to the Esporte Interativo journalist who broke the news of Neymar's transfer, but what he said on twitter was that "We didn't say it was done. We said that the player would like to play in Barcelona, but Klopp doesn't want to sell him" - his very own words. Barca once again trying to unsettle a player through the media
Also it's too late in the window for Liverpool to even consider selling him, he's too important for their side - regardless of him being overrated, he's the one that keeps pulling them out of trouble with "magic" moments which guys like Mané, Firmino and Salah, although very good players, can't pull it off often enough.
Interesting to see people pointing out to Liverpool fans that Barca are doing to them what they did with Southampton and RB Leipzig. Fair to say van Dijk and Naby keita are staying this season, so it's not a good comparison, because by this custom, Coutinho too will stay even if Barca turn his head
