Olympique Marseille chief Pablo Longoria has been told he must up his bid for Arsenal midfielder Matteo Guendouzi.

The Gunners are prepared to sell the France U21 captain this summer after his time away on-loan at Hertha Berlin.

Longoria has made contact with Arsenal and intimated a willingness of paying €10m to sign Guendouzi outright.

However, Arsenal are insisting Longoria go higher if they want the young midfielder.

The Gunners are seeking at least €20m to sell Guendouzi this summer.
