ANDY ROBERTSON admits it was difficult to determine where it all went wrong for Scotland as their Euros campaign got off to the worst possible start at Hampden.

Steve Clarke's side crashed to a 2-0 defeat as Patrik Schick netted twice - the second of which came from almost 50 yards - on a thoroughly disappointing afternoon in Group D.

Scotland had waited 23 years to return to a major finals but failed to fire on the Euros stage and now face a seemingly impossible task in terms of qualification out of the group.

Clarke takes his side to Wembley on Friday evening before Croatia visit Hampden next week and skipper Robertson was frustrated at the manner of the costly defeat.

Robertson said: "It’s hard to put your finger on it just now. Everyone in the country wanted to get off to a good start.

"We were confident, excited, and it comes down to not taking our chances.

"You can't say we’ve not created, we’ve had some really, really good chances that we should have done better with. If you do better on that, then it’s a different game.

"It’s a tough lesson for us that at the highest level, at the best tournaments, you have to take your chances. Czech Republic did that, we didn’t."
