Moussa Dembele has been in prolific form for Celtic

West Ham have not made a £20m bid for Celtic striker Moussa Dembele, according to Sky sources.

A senior source at the club says reports of an offer for the striker are wrong and inaccurate.

The 20-year-old Dembele joined Celtic in the summer on a four-year deal and has made a very positive impression, scoring 19 goals for the Hoops.
