CELTIC striker Moussa Dembele has teased a 'big announcement' on Twitter along with a picture of him signing a document. 

The France Under-21 international has been the subject of much transfer speculation following an impressive debut season at Parkhead in which he scored 32 goals in all competitions. 

Dembele, who is currently out of action with a hamstring injury, put Hoops fans on high alert when he posted a picture of himself putting pen to paper with the message: 'They wanted me...#FrenchScoringMachine #BigAnnouncementAlert #StayTuned.'

The 21-year-old arrived from Fulham last summer and has since been linked with a host of clubs in the English Premier League as well as European sides such as Marseille and AC Milan.

However, Dembele has three years left to run on his Hoops deal and Celtic boss Brendan Rodgers laughed off speculation of a departure last month.

He said: “I counted the other day 10 clubs [that have been linked with him],” said Rodgers.

“It’s the time, isn’t it? Lots of speculation around him and others. It’s just the background noise.”
