Former coach: If Tyson were to train six weeks, he'd call Wilder in a minute.

Jeff Fenech twice trained world champion and believes 53-year-old could knockout King of W BC, Wilder, Transmission Periscope.

Tyson's impressive career lasted for 20 years, 1985-2005, defeating 44 of his 56 opponents with knockouts.

He still holds the record as the youngest heavyweight champion in history, which he achieved in 1986, only as a 20-year-old.

Despite having been retired for 15 years, Fenerch believes that with a little training, he'd still knock out Wilder in 60 seconds.

“Box is no longer the same. I guarantee if Mike Tyson was training in six weeks, he'd knock Wilder out in a minute.

He'd knock them off. If these guys are being spotted by Tyson Fury who's a great boxer, but there's no such thing as a strong boxing Tyson would kill them.

“They are not on the same level today.” /Periscope. com/
