Keane and his Republic of Ireland teammates are preparing to take on McGregor and Scotland in the final match of the 2011 Carling Nations Cup at Aviva Stadium in Dublin and the former Celtic loanee admits it would be nice to get at least one past the ‘Gers gloveman who he could not beat in a couple of Old Firm derbies in the 2009/10 season.
"That would be great. I would like that,” Keane said.
"As a striker you are always looking to score and Sunday will be no different.
"Allan's a top class keeper and we'll have our work cut out to beat him.
"We played with an awful lot of confidence against Northern Ireland and scored five.
"That's a big boost for us going into the Scotland match.
"For me the most important thing is building our confidence up and putting in a good performance in preparation for the Macedonia (Euro2012) qualifier."
And Keane admitted it will be a good opportunity to catch up with some of his old Hoops teammates in the Scotland squad.
"It will be nice to see a few of the Scotland boys I know from my time at Celtic,” He added.
"I'm sure it will be a tougher test for us than the Northern Ireland game.
"If you look at the squad we have and with new boys coming in I thought that we did exceptionally well."
