That’s the verdict of former Premier League star Clinton Morrison, who says the move will work out for all parties in the long-term.
Coutinho emerged as Barcelona’s top transfer target following the £200m sale of Neymar to Paris Saint-Germain last summer.
But they were forced to wait until January to sign the Brazilian, with Liverpool finally sanctioning a highly-anticipated £142m deal.
Coutinho experienced a slow start to life at Barcelona after returning from an injury but has since claimed La Liga and Copa del Rey medals.
Liverpool, meanwhile, have secured a top-four finish, reached the Champions League final and look like a real force going into the future in his absence.
Morrison doesn’t believe Coutinho will be ruing his decision to swap Anfield for the Nou Camp at the turn of the year.
“Nah, I don’t think he’ll regret it,” Morrison told Express Sport. “A club like Barcelona or Real Madrid come knocking on the door, you have to go.
“And that’s not disrespecting Liverpool, because Liverpool’s a massive club with great fans. But I can understand why he wanted to go. Barcelona are one of the best teams in the world, [who] play unbelievable football.
“You know what? It’s worked out for Liverpool because a lot of people said they would struggle without him but it’s galvanized the team and they look really good at the moment.
Barcelona paid Liverpool £142m to sign Philippe Coutinho in January
Clinton Morrison says Philippe Coutinho will have no regrets about leaving Liverpool for Barcelona
“He did struggle when he first went, [but] over the last few weeks I think we’ve seen the real Coutinho. And when [Andres] Iniesta leaves, he’ll be a regular and he’ll be a force in that side and you’ll start seeing the best of Coutinho because he’s a terrific footballer.
“So all-in-all I think it was a good deal for Liverpool, who got a lot of money and can invest in the summer, and Coutinho will be a star.”
Coutinho will return to Liverpool on June 3 when Brazil face Croatia in a World Cup warm-up match at Anfield.
The playmaker was named alongside former Liverpool team-mate Roberto Firmino in Tite’s squad for this summer’s finals in Russia.
Five-time World Cup winners Brazil will face Costa Rica, Serbia and Switzerland in Group E.
