Alex Bruce believes Celtic could pick up in the region of £4million from a sell-on fee if Lyon cash in on former Bhoys star Moussa Dembele this summer.

The former Kilmarnock centre-back, speaking exclusively to Football Insider assistant editor Russell Edge, is convinced a £40million price tag on the 23-year-old is realistic after his outstanding form in France.

As revealed by Football Insider, Celtic are set for a significant windfall this summer thanks to their sell-on clause, worth more than 10 per cent, as Lyon prepare to sell their star striker.

It is understood that the decision to cancel the Ligue 1 season early may see French sides offload their top stars in a bid to cover losses and fill an estimated £175million financial hole.

Dembele has regularly been linked with a move back to the British Isles, with Manchester United and Chelsea both said to be keen on his capture.

With a potential big-money move on the cards this summer, Bruce believes Celtic could pick up in excess of £4million from a potential £40million move for the hitman.

Asked what sort of price Lyon could get for Dembele, Bruce told Football Insider: “Argh, bloody ****! £40million? £50million? You’d have to say around that in today’s market. I’m sure you’d be looking around that price.

“Obviously it all depends on what the market’s going to be like after this virus, it’s a very difficult question to ask. Around the £40million mark at the moment.

“He’s a really, really good player and for Celtic to get that extra bit of a cash injection if they do get that windfall then it’s going to be beneficial – as long as they spend it wisely.”

The decision to call the French top flight to an immediate end means that Lyon have missed out on European football next season, with Dembele and his teammates sitting seventh in the table.

The striker, who netted 51 times in 94 games for Celtic, has scored 22 goals across all competitions this season.
