Watford have announced the signing of goalkeeper Maduka Okoye from Eredivisie club Sparta Rotterdam on a five-and-a-half-year deal.

The Nigerian has subsequently been loaned back to the Dutch side until the end of the current campaign.

The 22-year old is 6ft6 and has kept one clean sheet so far this season in 13 appearances for Sparta, while he has also made 13 appearances for his national side.

He will join up with fellow Nigerians William Troost-Ekong, Emmanuel Dennis and Peter Etebo, should the Hornets exercise their option to acquire the midfielder permanently.

The German-born keeper has also represented Fortuna Dusseldorf and Jong Sparta.
