Arsenal face stiff competition from Barcelona for Sevilla midfielder Steven N'Zonzi.
Mundo Deportivo says Gunners boss Unai Emery is keen to be reunited with the Sevilla midfielder ahead of first season at the Emirates.
But Arsenal have so far been reluctant to pay the World Cup winner's £40million release clause.
And the La Liga champions are ready to enter the race.
The Catalan club's first choice is Paris Saint-Germain midfielder Adrien Rabiot but that move is dragging on.
Barca boss Ernesto Valverde does not want to wait until the end of the window to complete a move.
