Olympique Marseille coach Andre Villas-Boas has paid tribute to Aston Villa signing Morgan Sanson.

AVB has lost Sanson, Kevin Strootman (Genoa) and Marley Ake (Juventus) in the last week.

AVB posted to social media: "At each departure, a bit of my heart goes with you, a bit of OM crosses the borders and an empty box remains in Marseille.

“While your smile remains in our memory, we wish you good luck, strength and courage. May you be able to make your dream come true and one day we will find you at the Vélodrome.

"See you soon".
