The Hoops star has been selected in Roy Hodgson's preliminary Three Lions squad for the 2014 World Cup and Bonner, who represented Ireland at Italia1990 while a Bhoys player, feels he can force his way into the starting shirt regardless of the fact he players in the Scottish top flight.
"If you're playing in the Champions League you're in the spotlight, that must be taken into consideration," Bonner told the Daily Record.
"When you play with Celtic, it mimics international football rather than club football.
"In the bottom half of the English Premier League, you're under pressure all the time and making saves. But it's not actually replicating international football.
"That's about making your big saves at the right moment. It's slower, very tactical. I think playing for Celtic in some ways replicates that because you're not going to be making saves all the time.
"Your concentration levels need to be right, you must have some sort of model that will keep your focus as a priority because you're not going get save after save or cross after cross playing here.
"So he definitely doesn't need to leave Celtic."
Bonner added: "I'm delighted for Fraser. I had a feeling it was going to happen although (England) goalkeeping coach Dave Watson is also a coach at Norwich.
"It was a huge decision to pick Fraser ahead of his keeper, John Ruddy. It was very professional of them to make it a choice based on ability, not on emotion."
