Amir Khan intends to return to the welterweight division after his loss to Saul 'Canelo' Alvarez in Las Vegas on Saturday.
The brave Brit battled early before being knocked out by Alvarez in the sixth round as the Mexican retained his WBC middleweight title.
Khan, who fought above welterweight for the first time, said his plan was to drop back down.
"I tried as much as I could and trained very hard for this fight," he said.
"Unfortunately, I didn't get the result I wanted. Although I feel strong at this weight, I am naturally a lighter fighter and plan to go back down to welterweight.
"But, I like to challenge myself and that is why I took this fight. I want to be the best, and to be the best I have to fight the best."
Khan troubled Alvarez early in their bout before the 25-year-old landed his big right hand in the sixth round.
The 29-year-old's record dropped to 31-4.
