Celtic's Moussa Dembele is struggling in front of goal right now.

Pundit Charlie Nicholas has told Sky Sports that he thinks Celtic would be lucky to receive another bid of £12million for striker Moussa Dembele given his recent form.

The Bhoys are back in European action this evening, as after finishing third in their Champions League group, they head into the Europa League tonight, taking on Zenit St. Petersburg at Celtic Park in the first leg of their last 32 clash.

Brendan Rodgers' men are the underdogs against the Russian giants, and will need the backing of the famous Celtic Park crowd to pull off something of an upset against Roberto Mancini's side.

Recent performances – such as the 1-0 defeat at Kilmarnock – haven't been impressive for Celtic, and striker Moussa Dembele is really struggling for form right now.

The French attacker has been a sensation for Celtic since his 2016 move from Fulham, scoring 32 goals in 49 games last season, before grabbing eight goals in his first 15 appearances in all competitions this season.

However, Dembele has now scored just once in the last 10 games for Celtic, and looks to be woefully out of form, even with the January transfer window and speculation over his future now over.

The Scottish Sun claimed last month that Celtic snubbed a £12million bid from Premier League side Brighton and Hove Albion, refusing to sell the striker – but pundit Charlie Nicholas now suggests that the Bhoys would be lucky to receive such a bid again.

Nicholas has told Sky Sports that Dembele's performances mean his value is plummeting, and Celtic need both him and Scott Sinclair to step out of their poor form and into a strong display in a big game.

“Celtic are not playing well at the moment. The energy levels will be high for a European night at Celtic Park but that is the only reason why they are marginal favourites,” said Nicholas. “Scott Sinclair and Moussa Dembele, the two players you expect to step up in the big games, are both out of form, while Leigh Griffiths is injured. Dembele would be lucky to attract another £12m bid with the way he's been performing,” he added.
