Those are the thoughts of former Reds midfielder Paul Ince.
Coutinho was the subject of intense interest from Barcelona over the summer and Liverpool rejected three bids.
The Brazilian was left out of the match day squad for the 5-0 defeat away to Manchester City yesterday, and he is continuing his reintegration back into the first-team.
Previously, Suarez stayed on at Liverpool for an extra season before joining Barca in July 2014.
And Ince thinks Coutinho needs to put the saga behind him now and concentrate on his football.

“Philippe [Coutinho] has to try to copy Luis [Suarez] the season after he was told he could not leave,” Ince told the Mail on Sunday.
“One thing about Liverpool fans, as long as Coutinho does things the right way, the fans will still love him.
“They will understand the lure of Barcelona and will not hold it against him, just as long as he does not spend his time moping or show the kind of body language Arsenal fans have occasionally seen from Alexis Sanchez.
“Coutinho does not strike me as that type of player.
“There were a few eyebrows raised at Barca’s £120m valuation and he will have to shine in the Champions League to show he is truly worth that kind of money.”
