"The Belgium midfielder joined us from Fulham in August, 2012, and scored on his debut three days later against Norwich City.
"He established himself as a key player in our starting XI and went on to make 250 appearances in total, scoring ten goals. "Mousa has been capped 82 times for Belgium and was part of the Red Devils’ squad that finished third at the 2018 World Cup finals in Russia. "We wish Mousa all the best for the future." The 31-year-old central midfielder had just six months left on his contract with the north London outfit and had been linked with two Chinese Super League sides, Beijing Guoan and Guangzhou Evergrande. But another club nudged ahead and have now sealed a transfer that could be worth up to £11m.
