Hull have completed the double signing of Porto midfielder Evandro Goebel and striker Oumar Niasse from Everton.
Brazilian Evandro, 30, has signed on a two-and-a-half-year deal for an undisclosed fee and is reunited with Hull's new head coach Marco Silva after the pair worked together at Estoril.
Senegal international Niasse, 26, has joined on loan until the end of the season. Niasse has spent the season playing for Everton's under-23s after he was not even given a squad number by Ronald Koeman and is yet to score a Premier League goal since joining the Toffees from Lokomotiv Moscow last winter for £13.
