“I’m delighted to see Maduka sign for Watford,” the 28-year-old said. “I’ve been speaking to him for a while about the different options he’s had, and I knew the club were speaking to him, so it’s great that it’s over the line.
“We’ve spoken about playing in England before, and I had mentioned Watford. He’s a very humble kid and he’s kept his cards close to his chest, but I did say if the chance came around he had to jump at it.
“He’s been part of the Nigeria team for the last two years or so now, and over that time he’s made some fantastic steps. He moved to Holland from Germany and it’s been incredible to see him take on the responsibility that comes with being a No.1.
“He’s a very reliable goalkeeper with a huge will to learn, and I think he’ll add a lot of strengths to the squad when he links up with us next year.”
Born in Germany to a Nigerian father and German mother, Okoye played in the youth ranks at Borussia Mönchengladbach, Bayer Leverkusen and Fortuna Düsseldorf before moving to Sparta Rotterdam in the summer of 2020.
