Rohl intrigued by Old Firm selection headaches

Rangers head coach Danny Rohl was "surprised" Celtic didn't push for more goals against Stuttgart on Thursday night and says it will be "interesting" to see who Martin O'Neill starts in goal for Sunday's trip to Ibrox.

O'Neill made eight changes - including back-up keeper Viljami Sinisalo in place of Kasper Schmeichel - for Thursday night's Europa League play-off second leg in Germany after Celtic were beaten 4-1 in the first leg at Parkhead.

One of the stand-ins, Luke McCowan, fired Celtic in front after 30 seconds with what proved to be the only goal of the game as Celtic bowed out 4-2 on aggregate.

"I think when you see the line-up from yesterday, the starting line-up, then I expect some changes," Rohl said.

"It's normal, they try to use the full squad.

"I was a little bit surprised after 1-0 that they're not trying to win this game, 2-0, 3-0, to have a chance. They keep the result until the end."

Denmark international Schmeichel, 39, has come under fire from Celtic fans for sub-par performances and was even booed in last week's first leg at Parkhead.

Sinisalo kept a clean sheet in Stuttgart and made six saves as Celtic won on German soil for the first time.

"But yeah, it will be interesting as well, the goalkeeper position, what he will do now, let's see," added Rohl.

"But we are prepared, we're focused on ourselves, we also have some interesting decisions to make.

"I know if everyone is available, it's also not easy for me in some positions, because there are more than two or three players who are ready for this game.

"It's a good situation. I like this, my players showed that they are ready, I think this is crucial and let's see what it means on Sunday."
