Liverpool legend John Aldridge believes Philippe Coutinho won’t be staying on long term basis with the club.Aldridge is sure of the fact that Barcelona will come back for the Brazilian midfielder after missing out on him this summer, but he has encouraged the star to give Liverpool the very best this season.He said "Make no mistake, Coutinho will come back. He's a lovely fella, he's a good family man, and Barcelona turned his head. It can happen."The move over there didn't happen to him but I'm sure he'll give us a really good season and wave goodbye next summer because Barcelona will come back for him, he's too good to be ignored.RELATED: Coutinho & Sanchez urged to emulate Real Madrid, Barca stars"He's just got to stay in form for Liverpool, put all this behind him and play with pride in the shirt."I understand why some fans are a bit unsure about him coming back but it'll only take a belter from outside the area, and we'll all be singing his name again."Liverpool is going to get a huge amount to reinvest into the team when he leaves, just like we did with Luis Suarez. Let's just enjoy him while he's here, and let's hope he can kick on even more."Coutinho will be available for Jurgen Klopp this weekend as Liverpool face Manchester City at Etihad Stadium in their Premier League game.
