Celtic and Germany midfielder Mika Baur has attracted interest from clubs in the Premier League, Bundesliga and Serie A, according to Sky Germany, with a potential transfer fee of up to €20 million being suggested.

Things have moved quickly for Mika Baur since he left SC Paderborn to join Celtic FC for a fee of around €6 million last summer.

After hitting the ground running in Scotland, Baur made his senior Germany debut in October, and he was most recently called up to the U21 national team, but was forced to withdraw due to injury.

According to Sky Germany, Baur's development in Scotland has attracted interest from clubs in the Premier League, Bundesliga and Serie A, with the report suggesting that he could become a major transfer target next summer.

With Baur under contract until 2030 and no release clause included in his deal, Celtic are under no pressure to sell and could demand a fee in the region of €15-20 million for the central midfielder, according to the report.

Baur has scored four goals in 19 appearances for Celtic so far.
