Liverpool must move quickly to replace Philippe Coutinho, former Reds striker John Aldridge has warned.
"I am not surprised but disappointed he [Coutinho] is leaving because he is a fantastic player to watch," Aldridge told BBC Radio 5 Live's Sportsweek programme. "£140million is a lot of money and Liverpool have to spend it wisely.
"They have spent £75million of it wisely on Virgil van Dijk - a player we have needed for some time in a leader at the back - but he [Coutinho] needs replacing and we have got to do it ASAP."
Leicester's Riyad Mahrez - a key player for the Foxes when they won the Premier League back in 2016 - has been linked as a potential candidate to fill Coutinho's shoes.
Sky Bet make Mahrez odds-on at 1/2 to join Liverpool this month.
Aldridge, who scored 63 times for Liverpool, believes the Algeria international must be considered.
"If you look at the way Coutinho plays, he [Mahrez] is very similar," Aldridge added. "He is older, he has played in the Premier League for some years and everybody has seen the ability he has got, so he ticks a lot of boxes.
"You need that type of player similar to Coutinho who sees that pass, can do something extraordinary outside the box, can bend it in the top corner and is good on free-kicks as well."
