Philippe Coutinho told Marca that he has endured a terrible year at Barcelona and his plight should come as a warning to Liverpool players about what might happen if they too jump ship.
He said: “I have not had a good season. My performances have been a lot worse than I expected they would.
“The only way to improve and gain confidence is through hard work, and I have been working hard.”
The Brazilian forced a move to La Liga in January 2018 and while his move to Catalonia earned Liverpool an initial £105 and a potential further £37m in add-ons, his departure made supporters furious.
Leaving midway through the season after faking injury and refusing to train left a sour taste in the mouth but his plight in Spain has made his absence a lot easier to bear.
That, the fact that Liverpool have improved tenfold in his absence and their Champions League triumph in Barcelona should come as a warning to other Liverpool players.
Jurgen Klopp’s Liverpool is as ambitious as any other outfit on the planet and there are only a few teams in Europe that could guarantee players what the German can.
Top players want to win silverware but few coaches in the world are as good at improving players as Klopp is and it would have been interesting to see what Coutinho would have been like after another three or four years under his guidance.
