Ighalo arrived at the club in January from Shanghai Shenhua, and one player in particular has stood out for him in training.
He said: "Anthony, since I came, he's been scoring goals and doing so well, fighting a lot. He is a great player, he has great technique.
"He can do anything with the ball and he's been doing fantastically well. I just hope he keeps going and scoring more goals and we end the season very well.
"Watching it from outside it's different. You only watch games every weekend and see how skilful he is. But I train with this guy every day. Every blessed day I train with him, and it's incredible what he does in training. He does it so easy.
"Sometimes in games, it's difficult to do it, sometimes you face a tougher opponent but this is someone who every day you see in training and say wow, he's a good player."
