Legia Warsaw midfielder Krystian Bielik is due to have an Arsenal medical today.

Arsenal are close to completing a deal for Bielik, who will have a medical with the club on Friday.

Bielik told Legia's official club website: "'I'm going to London to fulfil my dreams. I hope I will become an Arsenal player soon."

The 17-year-old Polish youth international is regarded as promising defensive midfielder but has made only six appearances in the Legia first-team this season
