Liverpool are showing an interest in signing a new goalkeeper, with reports claiming that Alisson Becker could be heading through the exit door this summer.
It could be a busy summer transfer window for the Reds as they look to replace some of their outgoing stars.
Mohamed Salah is the most high-profile name to be departing, with his exit confirmed earlier in the season.
Scottish defender Andy Robertson will also be leaving the club when his contract expires in the summer, leaving Liverpool with plenty of work to do in the market.
Incomings will be necessary to replace the outgoing players, while they could be looking to add more quality after a disappointing season.
Liverpool Eyeing 'Serious' Option

According to reports in Portugal, Porto goalkeeper Diego Costa is now emerging as a 'serious' option for Liverpool ahead of the summer transfer window.
It's been claimed that Liverpool goalkeeper Alisson is tempted by a move away from the club in the summer, with Juventus offering him a contract.
Costa is believed to have a release clause in his contract in the region of £52 million.
It would be interesting to see whether Liverpool are willing to pay that much when they already recently invested in Georgian goalkeeper Giorgi Mamardashvili.
Alisson will certainly need replacing, but it remains to be seen whether they will look for a new number one or number two.
Costa Hailed as 'One of the Best'

Costa has previously been labelled one of the best on the planet in his position, and he'll have some big shoes to fill if he does arrive at Anfield this summer.
Alisson has also been described as being one of the best in the world in recent years, while some even label him the best in Premier League history.
Although the Brazilian goalkeeper is coming to the end of his time at Liverpool, he's still one of the best performers in the Premier League.
Replacing him certainly won't be easy, but Liverpool have a bigger task in trying to replace Salah during the summer transfer window.
