Liverpool have reportedly agreed to get first refusal on Porto midfielder Fabio Vieira.
The Sunday Mirror claim the Reds will have the option to outbid anyone else for the 21-year-old former teammate of Luis Diaz, who has a £12.7m release clause in his contract with the Portuguese club.
Arsenal are among a number of clubs showing an interest in Vieira, who notched up seven goals and 15 assists to help Porto win their 30th Primiera Liga title earlier this month, but Liverpool have already shown guile in their transfer activity over the last couple of years and will make sure they get Vieira if they want him.
