Chelsea summer signing Mamadou Sarr arrived at Cobham for the first time on Monday afternoon and we joined him at our training base as the talented centre-half took in his new surroundings...
The 19-year-old excelled in the heart of Strasbourg's defence last season as the Ligue 1 side earned the chance of qualifying for Europe next season.
Chelsea moved to secure the talented France youth international's services and the deal was announced on Monday, the same day he visited Cobham for the first time.
