It's the first time Batshuayi has scored in the Premier League this season but stats prove that he has a better goals to minute ratio than anybody else.
"I've heard an awful lot about what Michy Batshuayi cannot do," Cascarino said in his column for The Times.
“But the one thing he can do is score goals and his record of one goal every 60.57 minutes makes him the most deadly striker in Premier League history.
"OK, he has only scored seven so far but, among players who have scored more than five, nobody has scored more often - and that includes legends such as Thierry Henry, Ruud van Nistelrooy and Sergio Aguero.
"Batshuayi is a throwback to the days of the supersub.
"These days you rarely send a player on with any expectation that they are going to score.
"Batshuayi offers a genuine threat and he should be appreciated."
