Kerr, who was McGeady's national boss from 2003 to 2005, doesn't think that's going to be a problem.
"We are seeing a lot more of him for Celtic in Europe and his league performances have been exceptional. He was outstanding again last Sunday and also showed how good he was when he played against Brazil for Ireland last week.
"But when a player is with a Scottish club it is sometimes hard to measure just how good he is. It is only in the Champions League and international matches that you can really judge them.
"That is because the league in Scotland is not competitive enough on a regular basis. Although Larsson is hugely admired outside of Britain, a lot of that was based on his performances in international football and in European games at club level.
"Aiden just has to keep his head down and keep doing well for Celtic in Europe and for Ireland. That is enough at the moment because he is still young. Who knows where he can go in the future but he may have to leave Scotland to make a bigger name for himself."
