Martial was named as one of two players whose most impressed Ighalo has been since joining Shenhua in January with fellow countryman Bruno Fernandes.
The Frenchman has often been criticized at United for his performances, but Ighalo has no doubts of his value for the club.
“Anthony, since I came, he has scored goals and done so well, fighting a lot. He’s a great player, he has great technique, “said Ighalo in a video chat with the official United website.
“He can do everything with the ball and he does very well. I just hope he continues and scores more goals and we are finishing the season very well. “
“Looking at it from the outside is different. You only watch the games every weekend and you see how skillful he is.
“But I train with this guy every day, you understand? Every blessed day I train with him, and it’s amazing what he does in training, you understand? He does it so easily, you know? “

“Sometimes in games it’s hard to do, sometimes you face a tougher opponent, but it’s someone who sees you in training every day and you say wow, he’s a good player . “
Ighalo scored twice in the FA Cup win over Derby County and also scored in Europa League victories against Club Brugge and LASK Linz before the current football suspension.
He should make a permanent change to Old Trafford after the current campaign is over.
