The Belgian took part in the contest on a Chelsea-branded field in Los Angeles, and posted video from the game on his Instagram account.
Some took that to mean the 24-year-old striker was endorsing a move to the Blues, but Lukaku dismissed such talk as “BS” on twitter.
The tweet read: “Smh... hearing all this BS again.. its just a 5 a side game people! Some of you need to chill”

That denial is unlikely to erase the concerns of the Everton faithful as Lukaku has been rumored to be on his way out of Goodison Park well before this Instagram post.
Lukaku has bagged 68 Premier League goals in four years at Everton, first joining the club on loan and then permanently from Chelsea for £28 million.
Earlier this June, he made comments about his future “having been decided” and added at the time that he wanted to both play in the Champions League and win the Premier League.
Until an announcement over said future is made, Lukaku is likely to continue hearing things all summer.
