Liverpool has placed Porto's Diogo Costa on their shortlist as they prepare for the possible departure of Alisson Becker, who is attracting strong interest from Juventus. The goalkeeper signed a new long-term contract with Porto last year which includes a release clause understood to be £52 million. While sources state Costa is Liverpool's main focus, their review also includes other names like Bart Verbruggen, Robin Roefs, and James Trafford.
