Callum McGregor has admitted Celtic are where they expected to be after two matches in the Champions League.

The Parkhead captain stated in the aftermath of the sobering defeat to Borussia Dortmund that three points from their first two outings was a "realistic" position.

Brendan Rodgers had been bullish in the lead-up to the tie in Germany and was confident his side had the ability needed to take something from the match.

But, after the heavy defeat, McGregor appeared to suggest those within the Celtic changing room knew it would be a huge challenge to draw or defeat Dortmund in their own intimidating stadium despite making a winning start to the league phase last time out.

On TNT Sports, McGregor said: "We didn't do enough tonight. We came up against a good side.

"We have to stick together. We have had a good start to the season.

"We have still got three points. I think if we are realistic, then, we are where we thought we would be after two games so we take that and move on."
