Sunderland defender Sebastian Coates is a step closer to leaving Wearside on a permanent deal, according to reports.
Reports in Portugal claim Coates is set to agree to a pay-cut in order to win a five-year deal with Sporting Lisbon, where he is currently on an 18-month loan.
Coates has impressed officials at the Portugese side this season and they are understood to be keen to make his move a permanent one.
Sporting are reported to have an option to buy the Uruguayan centre-back at the end of the season for £4.5m but reports suggest that may happen sooner, in January.
It would be a welcome transfer boost for Sunderland, who will need to strengthen their squad in January.
Portuguese newspaper Record claim the 26-year-old is willing to accept a reduced salary with the Portugese giants.
Coates joined Sunderland from Liverpool in the summer of 2015 for £2million.
He has made 14 appearances and scored three goals so far this season.
