Lille have been ordered to pay Sporting Lisbon €20million - around £17m - by the Court of Arbitration for Sport (CAS) to settle their dispute over the transfer of Rafael Leao.
The news is good for Arsenal, as the French outfit may be forced to sell Gunners targets Renato Sanches or Jonathan David in the summer to raise the cash.
Lille could also be forced to offload Newcastle target Sven Botman.
