Will feel embarrassed when Coutinho returns to Liverpool. Didn't Klopp ever say to Coutinho that "don't go from liverpool, because you will succeed here". And it was proven, after Coutinho left liverpool. What happened to Liverpool, they are terrible right now. So there is no place back for Coutinho in Liverpool.
Yes i remember those opinions before that Klopp already says with many times that he suggest to Coutinho do not go to Barcelona because he need him and Klopp says too in Liverpool he will became an star player but in Barcelona he will became an mediocre player and seems Klopp statements was happened that Coutinho has been failed to compete with other players and Barcelona also confirm Coutinho as the failed purchase
