Arsenal midfielder Matteo Guendouzi is starring at Olympique Marseille under coach Jorge Sampaoli.

Guendouzi is on a season-long loan at OM and Sampaoli is bringing the best from him.

France youth coach Sylvain Ripoll said: "Sampaoli's personality, the discussion he was able to have with the coach, the feeling, were very important. He measured all that and he saw very clearly in his choice.

"I felt he was very excited to join Marseille. He has a tactical culture, a curiosity for the game and he is very interested in collective balance.

"With a trainer, he asks questions, he wants explanations and to understand them. At OM, things are bubbling up and it's a very good step for him. He must sometimes learn to channel his energy but he must also keep at it."
