In the first half of a pre-season trouncing of third-division Dutch side Excelsior Maassluis, Greenwood struck his first goal in the 28th minute and had secured the match ball just 11 minutes later, as reported by Foot Mercato. Marseille led by five at the break and that way it would stay at full-time, as head coach Roberto De Zerbi made a full eleven changes at half-time and the likes of Greenwood were substituted.
