Liverpool sold the Brazilian play-maker to Barcelona 18 months ago.
He told his Sunday World column published online by the Irish Independent, suggesting that no one at Anfield will have forgotten the manner in which the Brazilian jumped ship for Barcelona 18 months ago.
The 27-year-old moved to the Camp Nou from the Reds in January 2018, for a fee believed to be worth £142 million according to BBC Sport, but he has really struggled in Spain, racking up just 21 goals and 11 assists in 76 appearances in all competitions for the Catalan giants.
Coutinho is currently paid £240,000 per week at Barca, according to the Express, and ESPN claims that he could be sold for somewhere in the region of £90 million this summer, so he will be an incredibly expensive acquisition for Liverpool.
And Aldridge warned Jurgen Klopp against bringing the Brazil international back to Anfield this summer, when speaking exclusively to the Irish Independent:
"Coutinho left on a sour note as he forced his way out of the club and while he is a great player, I don't think Liverpool should blow their transfer budget on bringing him back. None of us have forgotten that Coutinho left Liverpool in a difficult position when he jumped ship mid-way through the season, so we should not give him a simple route back to play for the European champions."
Liverpool are already an incredibly strong side, so it is hard to suggest an area where they could actually improve.
Another world-class centre-forward and a creative midfielder might be on Klopp's wish-list, but after a year-and-a-half of heavy spending, this summer might just be a quiet one at Anfield.
