Michy Batshuayi came off the bench to score twice as Antonio Conte’s side came from behind to beat Watford 4-2 on Saturday.
For former Chelsea striker Tony Cascarino, the Belgian is the deadliest striker in the history of the Premier League due to his goal per minute ratio.
“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.”
