The 16-year-old Luxembourg midfielder is rated as one of the brightest prospect in world football and has already made his debut for Ligue 1 outfit Metz.
The teenager has already been capped seven times for Luxembourg since making his debut for his country back in March 2016. Several European clubs have been keeping tabs on Thill and was linked with a move to Real Madrid a few months back.
However, according to Italian website Calciomercatoweb (via talkSPORT), Arsenal and Bayern Munich currently lead the chase for the Luxembourg’s signature. It’s thought both clubs are in talks with the youngster over a possible transfer, but Metz are reluctant to sell their young star.
