But now Khan has admitted to Gary Neville on the former Manchester United footballer’s Overlap podcast it was a terrible mistake that he still can’t understand.

Khan, 35, said: ‘I was in the papers for crazy stuff – messing about with women, chilling out with this girl, chilling out with that girl. I was going through a bit of a mad time myself. I wanted to leave my wife then.

‘I had the problem with Anthony Joshua which I feel really bad for because at the end of the day I put him in the firing line for no reason.

‘I mean he was a friend of mine and since then we’ve never spoken.

‘So I lost a good friend through that as well.’

Asked if he knows now why he did it, he said: ‘No. What happened was, so my wife – me and her were not talking – and she sent a message saying “look so many fighters messaging me”.

‘And because she showed me a message of Anthony Joshua saying hi to her or something, I lost it.

‘I said “Who the hell’s he, saying hi to my wife”, even though he was cool with me.

‘Maybe he was just being respectful, all he was was being respectful. Nothing ever happened.

‘I just flipped out on everyone.

‘And all my mates were “are you mad, you just tweeted something”.

‘But he’s a nice guy. Even his own personal friends were calling me.

‘I was like “no, don’t want to talk to you guys”.

He later announced his retirement from boxing in May with a record of 34 wins from 40 bouts

‘I had to come through that difficult patch because at that time when I needed people’s help they weren’t there for me.

‘So I wanted to then do things myself my way. I become too selfish. I started making a lot of mistakes.

‘I started turning nasty – becoming a bad person really. It was never me and I was never happy with myself doing all this stuff.

‘I was really upset deep down. I was hurt and I was in a very, very bad position at that time.’

In his infamous tweet accusing Joshua, Khan also wrote: ‘Lol moved up in the weight classes lol. Trust me I ain’t the jealous type. No need to send me pictures of the men you’re talking to #Disgusted.

‘Left my family and friends for this Faryal. I’m not hurt but another fighter. I’m making it public. You getting the divorce #Golddigger. Mans like Joshua can have my leftovers!’

Joshua immediately denied the allegations, simply tweeting the same day a video from Shaggy’s famous song ‘It Wasn’t Me.’ And when asked by a fan this year if there was any truth in it, Joshua joked: ‘Honestly I didn’t. With all the accusations around me name I wish I did.’
