Arsenal are advancing on talks over a deal for for Valencia centre back Cristhian Mosquera.
The 20-year-old had been close to agreeing a move to the Bundesliga with Red Bull Leipzig but despite offering a decent contract, the German side failed to agree terms with Valencia.
Bayern Munich and Bayer Leverkusen had also posted interest but it is Arsenal who have now come to the fore.
The Spain youth international is the north London club’s preferred defensive choice to reinforce their backline.
He has made 90 appearances for the La Liga club in total, featuring in 37 of Valencia’s 38 league games last season.
