British boxer Amir Khan has made a blistering return to the ring by beating Phil Lo Greco by knockout inside 39 seconds at Liverpool's Echo Arena.
London 2012 Olympic champion Joshua had yet to start his professional career then but Khan, who has put aside differences with the heavyweight's promoter, Eddie Hearn, to sign a three-fight deal has been impressed by what he's seen.
He looked strong and void of any flesh on the scales but his opponent Lo Greco appeared relaxed - even more so than he has in the build-up to this event - and is confident of taking advantage of Khan's ring rust.
"It does feel back to business again, and this is the business I love doing", the 31-year-old told Press Association Sport. I wanted to prove a point.
"I have been out the ring for two years but I was still in the gym working hard, I have never taken a day off". It's great to be in a position now where I can make it back to the top again.

The Canadian has also goaded the Bolton-based fighter by suggesting he still has mental scars from the way Alvarez brutally knocked him out in 2016.
"Especially in his last fight, the way it ended, I know it's been on his mind for a long time".
"The weight is an issue with Kell, I'm a 147-pound fighter", Khan said after the win.
