Celtic could be in line for a cash windfall with Spanish giants Real Madrid and Barcelona preparing to battle it out for Jeremie Frimpong’s signature.

The full-back, who moved to Parkhead from Manchester City’s academy in 2019, spent 18 months in Glasgow’s east end before sealing a switch to the Bundesliga with Bayer Leverkusen in a deal worth around £11.5million.

Celtic included a sell-on clause in the transfer, meaning the cinch Premiership champions are due a cut of the fee when the Dutchman moves on, and that payday could be arriving in the not-too-distant future.

Spanish outlet Mundo Deportivo have credited both Barcelona and Real Madrid with an interest in the 22-year-old, who is out of contract in the summer of 2025.

It is believed that Leverkusen are holding out for a fee of somewhere between £30m and £50m and should the deal go through, Celtic will receive a sizeable sum.

Meanwhile, Portugal manager Roberto Martinez insists Jota looks to have found a place to flourish as he builds on the early stages of his career.

Martinez is keen to see one of his international hopefuls continue to develop under Ange Postecoglou’s stewardship in the 'perfect environment,' before he inevitably moves on to earn Celtic a big profit on their investment.

“It's about being consistent,” the 49-year-old explained. “Wide players, players that can make the difference they rely on the service they rely on how their team plays.

“I think what has been very good is that he’s been very consistent with this role. Obviously, you're talking about that position we have players like Joao Felix, Rafael Leao. The position is big in terms of competition for places, but he's evolved immensely.  

“When I look back at his time at Benfica and he had his time in Spain, I think he's found home. I think he really suits Celtic and I think it'll be very interesting how he develops in the next few months.  

“I think it’s the perfect fit for him, a club like Celtic - big games, being able to play Champions League, it’s made his evolution a very important one. 

“Every player fits into a way of playing. The way Celtic are playing, they rely on players with natural talent who can make a difference and take advantage.

“When you can see the confidence that Jota is playing at the moment, then he can come up with moments like the goal against Rangers, a header, that's very unusual! He's just been in the right place at the right time, and I think it shows you that he's playing with confidence.  

“That is down to the environment that the manager has created. It is the perfect environment for Jota to carry on developing.”
