Celtic have been declared as Scottish Premiership champions after it was decided that the season cannot resume.
The campaign had been suspended due to the coronavirus pandemic and amid lockdown measures in Scotland.
The final league table has been decided on a points-per-game basis, and Celtic have won the title for the ninth season in a row.
The Hoops’ bitter Old Firm rivals Rangers have finished second, and Dembele has brutally mocked Steven Gerrard’s side on Twitter.
The 23-year-old Frenchman, who was on the books of Celtic from the summer of 2016 until the summer of 2018 when he moved to French club Lyon, has trolled Rangers on Twitter while replying to a post from former Hoops striker Chris Sutton.
Thought Rangers won the league last time the way they celebrated on derby day ️?! On the brighter note 13pts gap is still not bad compare to 39pts in the Invincible season

Ligue 1 in France has also been called off early due to the coronavirus pandemic.
Lyon have ended the season in seventh place, with Dembele scoring 16 goals and providing two assists in 27 league matches.
