Barcelona are reportedly huge admirers of Liverpool defender Andrew Robertson.
Robertson, who joined Liverpool from Hull City in 2017, has been in fine form for the Reds this term.
The 25-year-old has contributed 13 assists from left-back, with his energy and work-rate a key feature of the success that Jurgen Klopp's side have enjoyed this season.
According to Mundo Deportivo, Barca are big fans of the defender, although the Spanish champions accept that it would be difficult to convince Liverpool to sell one of their key players.
The Merseyside giants have made the Champions League final at Barca's expense - overcoming the Catalan giants 4-3 on aggregate in the semi-finals - while they will look to land the Premier League title ahead of Manchester City on Sunday afternoon.
Barca, meanwhile, have already won La Liga, and will face Valencia in the Copa del Rey final later this month.
