According to Sport, Barca have been planning a move for Carlos for a little while now after he enjoyed a strong La Liga campaign in 2019-20 before the competition was suspended.
The 27-year-old has a buyout clause of €75 million which is too high for Barca, given the attacking signings they are planning, but they are confident they can negotiate.
One factor that might help swing a deal is Ivan Rakitic. The midfielder is surplus to requirements at Camp Nou but would be happy to return to Sevilla.
Barca did want €20m for the Croatia international, a fee Sevilla are unlikely to meet, but it’s possible the club could strike a deal involving the two players.
Yet Sport reckon there might be one more problem. Liverpool are also said to be keen on the centre-back and want to sign him to play alongside Virgil van Dijk.
The report reckons the Reds might even be in a position to pay his buyout clause and bring him to Anfield.
