Tom Allen was taken aback by Anthony Joshua’s powerful punch as the pair jokingly faced off against each other on The Jonathan Ross Show on Saturday, 6 April.

The two-time former unified world heavyweight champion practiced moves with the comedian such as a jab and an uppercut.

Allen’s moves sent Joshua playfully jumping into the air.

After Allen had a go at punching, the two swapped places with Joshua demonstrating his impressive strength.

As he demonstrated his uppercut, Joshua knocked Allen backward.

Asked whether trash talk can affect him, Joshua replied: “100 per cent. You take it personally and you meditate on it. You want to punish them for what they said about you.”

The so-called ‘Battle of Britain’ is one of the most highly-anticipated heavyweight fights in recent history.

But despite multiple attempts at getting the blockbuster clash over the line, it has yet to come to fruition.

Boxing fans have been clawing their eyes out waiting for the heavyweight titans to meet in the squared circle and luckily for them, it looks as though the long-awaited fight will happen sooner rather than later.
