Barcelona's board are discussing how much they should put Samuel Umtiti up for sale.
The Mirror says Arsenal think they have a chance to spring a surprise and sign the World Cup winning centre-back.
They feel the club's good relationship with the La Liga leaders could help swing things in their favour should they be willing to sell.
Umtiti only signed a new contract in June - and if what's rumoured is correct, it includes a release clause of a staggering £430million.
But there are claims in Spain that the Catalan giants would be willing to part with him as they attempt to lure Ajax centre-back Matthijs de Ligt to the Camp Nou.
Barca, though, have yet to name their price - and may not be willing to talk until the summer.
