The Briton is training in Oakland, US for what will be his first fight in almost a year against an opponent to be named and has focused all his efforts on meeting the vacant world title winner this weekend.
Khan had been linked to a massive UK battle with IBF belt holder Kell Brook, although that fight is seemingly off the table despite big interest from Eddie Hearn.
“I’m training for the end of March. That’s when I want to fight next,” said Khan via video from his current training base.
“I’ve got a few options. Danny Garcia is fighting for the WBC title. Even though I’m the No 1, he’s got the opportunity to fight for it, him being the No 2.
“I think I’ll get my chance to win that title against him and have that rematch which I’ve been looking forward to for a long, long time.
“I’d quite like that to happen this summer. If he wins that is, I’ll beat the winner of Guerrero-Garcia.”
In the video, the 29 year-old makes no mention whatsoever of any possible meeting with Brook in the future.
Brook will be fighting Kevin Bizier in a mandatory defence in March, but will have to look at alternative options to Khan for his planned summer outing.
