Liverpool remain in the hunt for Sporting CP wing-back Nuno Mendes.
The Reds made an offer of £19million for the left-back, which was rejected by Sporting, who would have accepted £40m.
But in response to the flurry of interest in Mendes, Sporting plan to tie the youngster down to a new contract with a £63m buy-out clause in the coming weeks.
Record says Liverpool's interest in Mendes is 'concrete' despite them not being in urgent need of a left-back.
The player could potentially move next summer with Real Madrid, Manchester City and Manchester United also interested in the highly-rated wonderkid.
But the reports in Portugal say Liverpool are the only club to have made an offer already.
