Musonda was once considered Chelsea’s brightest young prospect, scoring on his full debut for the Blues at the age of 20.
But the Belgian suffered an injury for two years, having only played four times during that time due to a knee problem that left his career in doubt at one point.
Musonda was pictured in training with the senior squad over the summer but was excluded from the Premier League and Champions League squad by Thomas Tuchel.
With his future at the club uncertain, the attacking midfielder has now spoken on social media, thanking fans for their support and vowing to come back stronger than ever.
“Hey guys, I’m in great shape and working out, an announcement about my future is coming very soon,” he wrote on Instagram.
“No one can stop someone who never gives up, I will be back at the top level, for now I can continue to work in silence and gain momentum, with my conviction still intact, thank you for the support.”
Musonda enjoyed an impressive loan spell in Spain with Real Betis in 2016.
He joined Celtic in January 2018 on an 18-month loan deal, featuring a Europa League victory over Zenit St Petersburg only for the loan to be terminated soon after due to a lack of time from Game.
In the summer of 2018, he joined Vitesse Arnhem on loan where he suffered a career-derailing posterior cruciate ligament injury.
