Amir Khan insists he is giving no thought to the prospect of fighting British rival Kell Brook as he prepares for the unenviable task of taking on Terence Crawford in New York.
The WBO welterweight title will be on the line at Madison Square Garden on Saturday, as Khan (33-4), faces Crawford, who is undefeated in 34 fights and rated as one of the best pound-for-pound boxers in the world.
Brook has flown out to the United States and will be in attendance for the fight, after his long-held hopes of fighting his domestic rival were again scuppered as Khan took up the opportunity to fight for a world title.
But the challenger to Crawford is not wasting any mental energy thinking about the activities of Brook, who has claimed he is actually there to seek a bout with the American.
Khan told Omnisport: "My whole focus is on this fight, the other names don't come any closer.
"There are a lot of fighters out there who would want to fight me or who I could fight but at the moment all my eyes are on one fight which is against Crawford."
Now 32, Khan insists his body is not showing signs of wear and tear from a long career.
He added: "It's hard to say [how long I have left in boxing]. I take every day as it comes and every fight as it comes.
"So I'm just enjoying the sport as much as I can and then hopefully my body will tell me when to call it a day, but at the moment I've got a lot of love for the sport, I'm still going strong. I still feel and am training like I did at 21."
