Leeds began tracking the 17-year-old several months ago and he was in the sights of Premier League side Brighton before United tabled a successful offer last week.

Bogusz visited their Thorp Arch training ground earlier in the month and flew back to England over the weekend to put the finishing touches to his transfer.
