Arsenal are jumping into the transfer row over Atletico Madrid winger Gelson Martins.

Currently on-loan at AS Monaco, Gelson is at the centre of a clash between Atletico and former club Sporting CP.

Sporting are still seeking compensation from Atletico over Gelson's summer move last year.

A Bola says Arsenal are ready to step in with offers to BOTH clubs in order to sign the Portugal international and end the dispute.

However, even Monaco could complicate matters where coach Leonardo Jardim is eager to keep hold of Gelson.
