John Hartson has told BT Sport's live pre-match coverage of Celtic's Champions League clash with Anderlecht (broadcast on 5th December 2017 from 19:00) that the Hoops could perhaps be just two signings away from tempting Moussa Dembele to ignore interest from elsewhere and stay at Parkhead.
Dembele is one of the brightest striker prospects anywhere in Europe right now, and has seemingly been linked with a move away from the Bhoys ever since he arrived from Fulham.
The Scottish Sun recently reported that AC Milan and some English sides are keen on the Frenchman after his excellent spell with Celtic. But former Hoops striker Hartson believes that showing some ambition in the transfer market may make Dembele consider whether he actually wants to leave in the near future.
"If they can add one or two of quality - they don't come cheap - that will appease Dembele and it might just twist his arm in terms of, 'you know what, I quite like what I'm seeing here and I'll stay'," he told BT Sport.
"What's to say if he went down to a Premier League club he'd play? He might not be playing every single week. The fact is up here, they could keep qualifying for the Champions League, play in front of a great crowd, he's playing with other top, top players and that might just be the key to keeping Dembele."
It would undoubtedly be a fantastic statement from Celtic if they managed to keep Dembele for a few more years given the level of interest in him since he burst onto the scene at Craven Cottage.
And Brendan Rodgers will be hoping that if they can keep him, that will help them in the transfer market as potential targets will see that Celtic are no longer willing to sell their best players for anything other than a ridiculous offer.
And that should then, as Hartson expects, have an impact on Dembele's mindset, as it will surely help convince him to stay for even longer if the team around him is getting better and better and it seems as so the ceiling is not too low in comparison with his ambitions.
