Barcelona are set to move for Chelsea captain Cesar Azpilicueta after confirming the departure of Dani Alves.
But Thomas Tuchel is fighting to keep him at Stamford Bridge.
Barcelona have already offered the player a 2-year-contract.
This is a move aimed at fortifying the Barcelona defence. Sergino Dest is also hopeful of continuing his Barcelona career while Sergi Roberto has just signed a new deal.
The 32-year-old began professional football with Osasuna before joining Marseille in 2010. He signed for Chelsea in 2012 and has won everything to win there including the Champions League.
Azpilicueta has also earned 40 caps for Spain.
Xavi wants to bring experienced players to Camp Nou to complement an exciting core of young players.
