The Belgian has already set a new milestone for the club before even taking the pitch...

Romelu Lukaku hasn't even worn a Manchester United jersey in a pre-season game, but he's already breaking records with the Red Devils.

The Belgian striker became part of the team's social media history, as the annouuncement of his £75M deal with the club set a new Twitter record for the club, as the most retweeted story in their social media feed.

The team's website claimed that Lukaku "carved out a small piece of history" with this feat, and now, the Belgian will have to live up to all the expectations from fans and experts.

The previous record-holder was Paul Pogba, who's comeback story last summer gathered 88,000 retweets. 

Lukaku is expected to make his debut with the Red Devils this Saturday, when Mourinho's team starts its U.S. tour against the Los Angeles Galaxy.
