Lennox Lewis has been closely following Deontay Wilder's career over the years.

Through his work with PBC and FOX Sports, Britain's greatest ever heavyweight has got to know the Bronze Bomber on a more personal level.

Lewis, 56, currently serves as an analyst for the network's boxing coverage, including Wilder's trilogy of fights with Tyson Fury.

More recently, Lewis was seen congratulating the Gypsy King on his victory in Las Vegas - just as he got out of the shower.

But he has also spent plenty of time in the company of Wilder and footage from 2013 shows him giving him a boxing lesson in how to throw the perfect jab.

In the video clip shared on Twitter, the 56-year-old ring legend can be seen instructing how to position the left hand correctly before throwing it with pinpoint accuracy.

The 28-year-old Wilder stands almost in complete silence as he watches his every move.

At one point, Lewis tells Wilder to stop to allow him to make a minor correction to his stance, before the latter carries on repeating the technique as he tries to perfect it.

Those who are paying close attention probably can't help but notice the rather impromptu training session takes place in what appears to be the car park of a nearby hotel.

But Wilder didn't seem to mind in the slightest as he thanked Lewis for taking time out of his evening to give him a lesson in the sweet science.

At the end of the clip, Wilder can be heard saying: "You know what it takes to be a champion and I'm somebody trying to get there."

Lewis replied: "Don't worry, you will."

He added: "Alright man", before walking back to his hotel.

The clip ends with Wilder saying: "Y'all [sic] have a good night."

It seems Wilder took the advice on board as he beat Bernard Stiverne at the MGM Grand in Las Vegas to win the WBC heavyweight title two years later.

In doing so he became the first American heavyweight world champion for almost a decade dating back to Shannon Briggs in November 2006.

The 36-year-old defended his WBC title nine times before losing it in a rematch to Fury two years ago in February 2020.

He is the first choice for Anthony Joshua according to Eddie Hearn but it remains to be seen whether he will retire or not.
