Barcelona and Atletico Madrid have opened talks on a swap deal involving Antoine Griezmann and Saul Niguez.

Griezmann left Atleti for Barcelona in 2019 for a fee of €120 million, but the club is open to letting him go. While Griezmann would be fine remaining with Barcelona until his contract runs out in 2024, he's also willing to return to Atleti. 

After Messi, Griezmann was the biggest earner at the club last summer and his departure would create the most room on the wage bill.

Talks are ongoing as Barca value Griezmann higher than Saul.
