Talented 18-year-old Sporting Lisbon starlet Nuno Mendes has delayed signing a new contract at the club amid interest from Liverpool.
Mendes has impressed this season and was previously linked with Leicester and Newcastle.
The left-back is also a target for the Reds, according to A Bola, who report that he does not want to deter them by increasing his release clause in a new deal, which already stands at £40m.
They claim that Liverpool would 'back out' of signing him if the release clause is made higher.
Mendes already has a long-term contract with the Portuguese side, who have produced an array of talent over they years, including Cristiano Ronaldo.
