Khan recovered from a second-round knockdown to beat Colombian Samuel Vargas on points at the weekend, and speaking after the fight Eddie Hearn, who promotes both Brook and Khan, suggested a grudge match between the British pair must happen “now or never”.
Khan told PA Sport: “I’m 31, I’m still young and there’s still room for both fights. Why isn’t there? I think within a year both fights could be done.
“Pacquiao is definitely my priority because he’s globally a bigger name, a superstar in the sport of boxing. To fight someone like him would be amazing.
“It’s a tricky fight and people will think I could get beat by him, but I know I can do a number on him.
“The Kell Brook fight is a fight I know I could win comfortably, really. It’s what name I want on my record. I’d love a Manny Pacquiao name over Kell Brook by miles. That name, in my opinion, is way bigger.”
While a stadium fight with Brook appears to be the preference of the British boxing public, Khan believes it could be possible to tempt Pacquiao over to these shores with a good offer.
He spent six years working alongside the Filipino under the tutelage of trainer Freddie Roach and believes that insider knowledge would be the key to victory should the two meet in the near future.
“In my opinion fighting someone like Manny Pacquiao would be amazing because we were training partners,” Khan added. “I know a lot about him, I’ve sparred with him and I do really well against southpaws. I’ve a 100 per cent record against them so that might be the right fight for me.
“We’ve always kept (the relationship) very professional. We’ve known we’ve wanted to fight each other for a long time, there’s always been talk about it but we’ve never talked about each other.
“We’ve respected each other’s careers, we’ve respected each other as fighters. It’s not like with Kell Brook and how the talks about that fight have been happening.
“Even in the UK I think a Manny Pacquiao fight would be huge as well. To bring Manny to England and have a fight over here would be massive.”
Khan will now target Pacquiao, but Vargas feels he should be careful what he wishes for.
“I think Pacquiao’s power is just too much. You, I think, Pacquiao stops him,” Vargas said.

After his exciting but flawed points win over Samuel Vargas in Birmingham on Saturday, Khan seemed to prefer a clash with faded legend Manny Pacquiao, his former sparring partner.
However, the British public, as well as Brook and Hearn, much prefer a huge stadium fight which would settle a long-running war of words between the Englishmen.
“It’s down to them,” said Matchroom boss Hearn.
“It has to happen next or it will never happen, so it’s up to these guys.
“There is only so much we can do; we will listen to the public, we know Amir wants Pacquiao and he will fight Brook. But it’s now or never for the Kell Brook fight.
“Amir will have two weeks off then we will sit round the table. Kell wants the fight and I know Amir will fight him.”
Khan, however, seems to prefer a more internationally-appealing scrap with Pacquiao, who he trained with under Freddie Roach.
“Both fights are massive but Manny is someone I’d love to fight first. I’ve always wanted that fight,” said the 31-year-old.
“Manny and I trained together and he’s a southpaw. I’ve got a 100 per cent record against southpaws and that would be a more technical, tactical fight.
“Let’s see what happens. At the end of the day we’re businessmen, and we do what makes financial sense.”
Khan had to climb off the canvas before comfortably beating the game, but limited, Vargas in Birmingham.
The Bolton welterweight, in his second fight since returning to the ring after a two-year absence, was knocked to the floor in the final moments of the second round.
Colombian-born Vargas had already been put down himself when he stunned Khan and the capacity crowd.
But, with Brook watching at ringside, Khan recovered and floored Vargas again before eventually running out the unanimous points winner.
The second round was only 20 seconds old when Vargas hit the canvas, sent on his way by a fearsome left jab.
He was up quickly but was immediately sent staggering backwards again amid more lightning Khan combinations.
But the elephant in the room, Khan’s fragile chin, let him down right at the end of round two as a long-range right hook left him on his backside.
