Real Madrid are monitoring the €20m 17-year-old striker with Bayern Munich and Manchester United

It doesn't take much for a promising youngster appearing in Europe's top divisions to catch the eye of the richest clubs these days, and in Charalampos Kostoulas match season, it is already the case. The 17-year-old is enjoying a promising campaign under Jose Luis Mendilibar at Olympiakos.

Able to play mainly in front, but also outside or behind the striker, Kostoulas was discovered by Real Madrid. Together with Los Blancos, West Ham United, Bayern Munich and Manchester United They are already paying attention to him, says the Sun (via MD). It could be available for 20 million euros.

Olympiakos will certainly be hoping to address their contract situation sooner rather than later. His current deal expires in 2026, and if they can't extend his contract, then the Greek giants will be required to sell him next summer or risk losing him for three. Kostoulas has three goals and one assist in his 18 appearances this season, and has featured in five of Olympiakos' six Europa League games.
