Arsenal face competition from Chelsea for Chivas Guadalajara striker Carlos Fierro.
The 17 year-old was linked with the Gunners earlier this week, with claims suggesting a deal worth €2.5 million was on the table which would see Fierro spend another year on-loan at Chivas.
However, Chelsea have been making enquiries after Fierro since January and enjoy a close relationship with Chivas thanks to last summer's deal for Ulises Davila, currently on-loan at Vitesse Arnhem.
Should Arsenal make good on their offer for the teen, Chelsea will be given the option of matching their bid.
