The 30-year-old joined the Red Devils on loan during the January transfer window and scored four times in his first eight appearances for the club before the majority of football across the globe was called to a halt.
"He's a wonderful athlete, I've never seen someone more passionate about their job than him," Ekemini Ekerette told Goal. "I think he's in excellent physical condition. He loves the game. He just wants to train. Even if the league wasn't going to played in the next three months he would keep training every day. He is so disciplined.
"His future was not making a difference to his intensity in training. He is just always focused on making sure he's doing what he needs to do and then pushing himself even further.
"He's a team player and has been talking about [Marcus] Rashford, [Anthony] Martial, [Mason] Greenwood, and how fantastic they all are, so he's looking forward to hopefully getting to play with Rashford. He wants to stay and loves United, Ole [Gunnar Solskjaer] and the fans and he would love to be a Red for the rest of his life."
