Amir Khan delivered an emphatic statement of intent by knocking out Phil Lo Greco after just 40 seconds.
After the fight, Khan quickly turned his attention to Kell Brook, who is looking for another big fight after suffering consecutive losses to Gennady Golovkin and Errol Spence Jr.in the last two years.
Speaking to iFL TV yesterday, former cruiserweight world champion Johnny Nelson said he expected Khan to be on top form in front of a sold out crowd in Merseyside tonight.
What a way to make your comeback. Lo Greco beat the count and then Khan battered him with punches that sent the Italian fighter down for the second time and the contest was waved off.
"I used to be sat ringside watching at fights and be missing the sport thinking, "Wow, I want to be back in the ring again".
As for a bout with Brook, Khan, most famous recently for his "jungle" appearance in the British television show "I'm A Celebrity, Get Me Out of Here", said: "That fight is something I am not rushing and not running away from". "He has the fastest hands I've been in with". That's what has always impressed me about him. Even if I have to cut both my legs off, I'll get there.
"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".
The 31-year-old former world champion followed up on the knockdown with an nearly maniacal assault against the ropes: Lo Greco swallowed a couple while slumped backwards before collapsing to his knees under fire. "I wanted to prove a point coming back - I was trained to fight for 12 rounds, I had to make some changes and Phil lo Greco is a risky opponent", Khan told the BBC.
