Marouane Fellaini celebrates after scoring against Albion

West Brom have apologised over a tweet about Manchester United midfielder Marouane Fellaini.

The Baggies posted a message on their official Twitter account about Fellaini during Monday’s 2-2 draw with United which was retweeted 20,000 times.

"Fellaini has now taken his tracksuit off, fortunately he has a Man Utd strip on underneath," Albion wrote on the social media site.

The Belgium international then scored just three minutes after coming off the bench at half-time.

United keeper Anders Lindegaard accused the club of a "complete lack of knowledge, class and respect" from his own Twitter account.

We are extremely disappointed that our tweet was taken out of context by mischief-makers. West Brom

However, Albion insist the tweet was taken out of context, with the club intending to joke about the possibility of Fellaini being naked - amid the cold outside temperature - under his tracksuit.

A statement read: "In response to incorrect and mischievous reporting, we would like to clarify that our initial tweet about Marouane Fellaini was made as the player removed his tracksuit top.

"That was in preparation for his introduction to the game during a period when night-time temperatures were dropping significantly.

"We are extremely disappointed that our tweet was taken out of context by mischief-makers.

"And that's not least on a night when two teams showed such a commitment to strident and attacking football to once more underline the quality and entertainment value of the Barclays Premier League."
