Celtic could land a significant transfer windfall should Jeremie Frimpong leave Bayer Leverkusen this summer.

The flying right-back, 23, has been linked with a lucrative move to Manchester United after lifting the Bundesliga title.

And any transfer switch for Frimpong will see Celtic receive a kickback from the profits.

The Netherlands international first signed for Celtic in a deal from Manchester City worth £350k back in 2019.

Celtic banked a major profit of around £11m when Frimpong left for Leverkusen in January 2021 for a reported fee of £11.5m.

And Celtic chiefs inserted a sell-on fee into the deal with the Parkhead club set to receive 30 percent of the profit should Frimpong be sold by Leverkusen.

But what does that actually mean for Celtic?

Well, Jeremie Frimpong's release fee at Leverkusen is reported to be £34m. That means it would likely take a bid in that region for the German club to part with the full-back.

And should a £34m bid be accepted by Leverkusen - by Manchester United perhaps amid speculation of interest from Erik ten Hag - then Celtic would receive 30 percent of the profits made by the German club.

In theory, if Frimpong was sold for £34m then that would mean Leverkusen profited £22.5m.

Therefore, Celtic would be entitled to a windfall in the region of £6.75m due to being entitled to 30 percent of the profit through their transfer clause.

Frimpong has caught the eye for Leverkusen in their incredible title-winning season with 13 goals and 11 assists in 40 outings for Xabi Alonso's side.

Leverkusen chief executive Fernando Carro previously admitted the club will likely sell one key player in the summer.

He said: "Every year we need to sell one big player to find budget for new signings.

"So, probably we will sell one player. We're planning to sign two or three players with that amount of money."
