Hull City have recruited Poland winger Kamil Grosicki for an undisclosed fee and signed Alfred N’Diaye on loan from Villarreal.
Grosicki penned a three-and-a-half year deal from Rennes. The 28-year-old has nearly 50 international caps and scored 13 goals in 85 appearances during his three-year spell at the French club.
N’Diaye returns for his second spell in England, having joined Sunderland in January 2013 and made 16 Premier League appearances that season.
The 26-year-old Senegal international went on to join Real Betis in 2014 before making a switch to Villarreal last summer.
The pair will be in contention for their Hull debuts when Liverpool visit the KCOM Stadium on Saturday 4 February.
