Real Madrid and Barcelona are reportedly monitoring Trent Alexander-Arnold ahead of a possible move for the Liverpool defender next summer.
Alexander-Arnold, 25, has developed into a star at Anfield ever since making his debut in 2016.
The academy graduate has racked up more than 300 appearances for his boyhood club, but has just a year left to run on his deal.
And, according to The Sun, El Clasico rivals Real and Barcelona are reportedly watching Alexander-Arnold's situation closely, with the England star yet to pen an extension with the Reds.
The report goes on to claim that both clubs believe Alexander-Arnold would be open to a move, particularly with his fellow academy right back Conor Bradley having significantly progressed over the past 12 months.

It is believed Liverpool are set to offer the 25-year-old a new deal that would significantly increase his current £180,000-a-week wages, although the club are unwilling to break the bank to keep him.
Reports have circulated in recent times in regards to a potential move to the Bernabeu, with these links only increased by Alexander-Arnold's friendship with Jude Bellingham, particularly after the pair recently spent time on holiday together in Los Angeles.
The report adds that it is unlikely the Reds would move on Alexander-Arnold this summer given the emotional connection between the player and his boyhood side.
However, he is one of a number of key players whose future is uncertain at Anfield, with both Mohamed Salah, 32, and Virgil van Dijk, 33, also heading into the final 12 months of their deals.
Alexander-Arnold has won seven trophies with the Reds over the past eight years, adding 81 assists and scoring 19 goals in 310 games.
He is viewed as one of the most complete passers in the Premier League, although it remains to be seen where he plays in new Liverpool boss Arne Slot's system, with the Dutchman said to prefer a more traditional right back, akin to Bradley.
As a result, Real and Barcelona, coupled with several other major European clubs, are keeping an eye on Alexander-Arnold.

Michael Owen, a fellow Liverpool academy graduate who made the move to Real in his mid 20s, recently tipped Alexander-Arnold to switch Anfield for the Bernabeu.
'Obviously Real Madrid at the moment are the best team in Europe,' he said. 'They are the biggest team in the world and have that iconic kit and their players… It's the best stage in Europe.
'I had a similar thing at that stage of my career, and I decided that it was an opportunity that I couldn't pass up.
'I don't know if it’s an opportunity for Trent or a possibility, but he'd have a lot to think about if they came in for him.'
