Championship side Wolves have signed Villarreal midfielder Alfred N'Diaye on a season-long loan deal.
Senegal international N'Diaye has made only nine La Liga appearances for Villarreal since joining from Real Betis in January 2016.
The 27-year-old joined Hull on loan in January, scoring one goal in 15 Premier League games.
He also played for Sunderland between January 2013 and August 2014, making 16 appearances for the Black Cats.

The very late announcement of the defensive midfielder Alfred N'Diaye's arrival at Molineux at least prevented Wolves from drawing a blank on deadline day.
A solid signing - but Wolves did not land the striker they so obviously need. Their plans were apparently scuppered by a change of heart from PSV Eindhoven, who were reportedly happy to accept an eight-figure offer for the forward Jurgen Locadia until early evening.
Leo Bonatini is therefore the only specialist senior striker available following the sale of Nouha Dicko on Wednesday, although a number of others in the squad can play in that role too.
Taking the window as a whole, Wolves were certainly busy bringing in players, but arguably they failed - for whatever reason - to fill the most important gap. Bonatini has made an encouraging start to his career in England, but he may find he is carrying a heavy burden for a while.
It remains to be seen whether this disappointment will at all affect the bouncy mood prevalent among most Wolves supporters over the last few weeks. Ultimately, results will decide that.
