Diego Costa is undergoing a medical at Wolves today.
Costa, 33, had his work permit accepted on appeal yesterday after it was initially rejected by the Home Office.
His original application was dismissed due to his lack of recent match-time at club level and recent lack of international appearances for Spain.
As soon as the appeal was granted, Costa was given the green light to fly to the UK for medical tests.
He landed last night, but arrived at Wolves' Compton training ground this morning.
The striker is set to sign a one-year deal with Wolves this afternoon, but he is not expected to be ready for the club's upcoming clash with Liverpool on Saturday, says The Sun.
Costa hasn't played a competitive match since December.
He made just 19 appearances for his previous club Atletico Mineiro before terminating his contract in January.
