The 17-year-old attacking midfielder has scored three goals and provided one assist in 11 appearances for Borussia Monchengladbach, establishing himself as one of the Bundesliga's most promising young talents.
Bayer Leverkusen are now monitoring his development closely, with Sky Sports reporting that the club have identified him as a potential long-term investment. Bayern Munich are also keeping tabs on the teenager, while several other clubs are understood to be following his progress.
Mohya's performances have even brought him into the thinking of Germany head coach Jürgen Klopp. Speaking before the national team's Nations League meeting with Serbia, Klopp confirmed that he had already spoken to the youngster and had not ruled out involving him.
“Obviously we haven't ruled him out. I spoke with Wael previously. Unless something changes, he won't be in the team. We want him to experience everything.
“If I imagine myself being 17 and someone telling me I could be part of a team like this, I would have taken absolutely any opportunity to make that happen. That's exactly how it is.
“He is training brilliantly and is in a great moment, but he hasn't been ruled out. He is here with us.”
The attention from Leverkusen adds another dimension to Mohya's rapid progress. The club are understood to see him as a potential attacking reinforcement for the longer term rather than an immediate solution to a shortage in their squad.
His contract at Gladbach runs until 2028, giving the club a degree of security, although the growing interest from leading Bundesliga sides could make negotiations over improved terms increasingly important.
Bayern's interest means Leverkusen would face competition if they decide to pursue a transfer. For now, however, Mohya's immediate focus remains on continuing his development and taking advantage of the opportunity to train with Germany's senior squad.
His potential involvement under Klopp would represent another significant step in a breakthrough campaign that has already put him on the radar of some of the country's biggest clubs.
