The 27-year-old failed to have an impact at Camp Nou after a disappointing return of 21 goals in 76 games in all competitions.
Liverpool have gone from strength to strength in Coutinho's absence - opening up a 22 point lead at the top of the Premier League after winning the Champions League, UEFA Super Cup and Club World Cup over the previous year - while the Brazilian has struggled to make an impression in Spain and is now on a season-long loan deal at Bayern Munich.
Since Coutinho's departure, Liverpool have won the Champions League and are on course to clinch their first English Premier League title in 30 years.
Philippe Coutinho says he has no regrets about leaving Liverpool, despite the success they have had since his 2018 exit.
"Coutinho served a objective at Liverpool and was an excellent participant for a time frame - however that point has gone".
"I'm happy with what I did in the past, and now I can only look forward". That wasn't the case at Liverpool and positively wasn't the case at Barcelona.
"I could see him slotting in perfectly at Chelsea, where Frank Lampard is doing unbelievable things trying to reboot that club using a lot of young talent bedding in alongside some experienced stars".
"Coutinho would feel really comfortable in the number 10 role at Stamford Bridge with the protection of N'Golo Kante and Jorginho and an array of young frontmen around him who would thrive working off him".
"The sticking level, after all, is that Barcelona would need foolish cash for him and I'm unsure Chelsea or Manchester United or Spurs could be ready to interrupt the financial institution to get him". "Stay here, and they will end up building a statue in your honour", Klopp told Coutinho.
