Bayer Leverkusen's chief executive has admitted that they will have to sell at least one player this summer. 

And this could well have Celtic awaiting their big payday from Jeremie Frimpong's potential mega money move to Manchester United.

Reports have circulated for months that Erik ten Hag is keen to take the Dutch international to Old Trafford this summer.

The right-back has played a pivotal role in helping Leverkusen secure the Bundesliga title. He has eight goals and seven assists so far this season.

Reports have suggested he has a release clause of £34m at Leverkusen. 

And if any deal does go through for that amount, then a sizable chunk of that will be headed in Celtic's direction, with the Scottish champions holding a sell-on fee with the German side for the future sale of Frimpong.

It appears he could well be on his way out of Germany this summer, with the club's CEO, Fernando Carro, admitted they may be forced to sell players to fund the defence of their title next season.

Speaking to Spanish newspaper Diario AS, he said: "Every year we need to sell one big player to find a 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."

Celtic are reportedly due 30 percent of the profit from the sale of Frimpong. 

So, as well as Leverkusen making money on the player, it could well prove to be a massive boost to Brendan Rodgers' summer transfer plans in Glasgow.
