The Catalan giants’ pursuit of the Brazilian playmaker ended in failure last night with the closure of the Spanish transfer window.
Barcelona had earmarked Coutinho as a key signing to replace the departed Neymar, who left the club for Paris Saint-Germain in a world record £198million transfer.
But despite signing Ousmane Dembele from Borussia Dortmund, Barcelona endured the unfamiliar outcome of not landing a key transfer target.
And Evans believes Coutinho will return to his best form for Liverpool despite seeing his dream move fail to materialise.
“He wanted to go but Liverpool said no,” Evans told The Two Mikes.
“Liverpool said you’re not going, we want you to stay. We’ve got a top player and we don’t want to become a team that sells their best players – and they’ve stood their ground.
“Obviously, it was a massive offer and his head’s been turned. And who wouldn’t want to go to Barcelona?
“But at the same time, you sign a contract at one club and sometimes you have to honour that contract.
“And to be fair to Coutinho, I’m hopeful that he’ll give his best. He’s that type of lad from what I’ve seen and he’ll go out there and play his best football and try and do his best for Liverpool.
“You can’t just have it your own way. You are contracted and sometimes you have to fulfil that [agreement].”
Coutinho’s international teammate Neymar revealed the Liverpool star was ‘filled with sadness’ and was apparently seen crying after hearing his move to Barcelona had broken down.
The 25-year-old has yet to feature for Liverpool this season due to complaints of a back injury but managed to perform for Brazil on Thursday night by scoring in a 2-0 win over Ecuador.
And despite concerns Coutinho may not be in the state of mind to perform to his best ability for Liverpool, Evans is hopeful the midfielder will live up to his professional manner.
“At the end of the day the World Cup is coming up and he has to get in the Brazil team,” Evans added.
“Hopefully he has an honest style about him and will think: ‘ok, I’ll accept the decision that Liverpool don’t want to sell me and I’ll play my best’.
“When the time comes he might get his chance in six months or a year’s time to move to Barcelona.
“I’m sure we’ve improved him in many ways since he’s come to Liverpool and he’s become one of our top players.
“It’s an exciting time to be at Liverpool. Jurgen [Klopp] has spent a lot of money on players. And certainly going forward we look a real force and I think we have a chance of starting to win trophies.
“It’s not as if we are a team struggling with nowhere to go. He is at a place where he is certainly going to get Champions League [football] and he can enjoy his football.”
