Scotland received a sobering lesson on their return to the major international stage as Steve Clarke's men went down to a 2-0 defeat to the Czech Republic at Hampden.
It leaves them with a huge uphill battle to qualify Group D with a trip to Wembley on Friday followed by the visit of Croatia to Hampden for the final fixture.
Bayer Leverkusen striker Patrik Shick was Scotland's tormenter in chief with a double - the second a stunning long range effort after catching David Marshall off of his goalline.
Shick admitted he noted Marshall's advanced position during the first half so he could make the most of his opportunity while Scotland captain Andy Robertson defended his goalkeeper.
Here is the reaction from Robertson and team-mates John McGinn and Stuart Armstrong along with Hampden hero Shick.
“It’s hard to put your finger on what went wrong right now. The whole country wanted to get off to a good start and we were confident and excited going into the game.
“It comes down to not taking our chances. When you look back on the game you can’t say we haven’t created.
“We had some really good chances that on another day we should have done better with and if you do better then it’s a different game.
“It’s a tough lesson for us in our first game in a very long time at the highest level because you have to take your chances when they come - Czech Republic did that, we didn’t.
“For the first goal, with the height of us we shouldn’t concede from second balls or set pieces.
“We were really good at clearing the set piece but you still have to pick up your man and defend it.
“To be fair to the boy it was a good header but we have to be a wee bit stronger and braver with our line and be a wee bit higher to make it more difficult.
“We started the second half really well, hitting the crossbar and we had a couple of really big chances and then Jack Hendry has a blocked shot and the boy’s in his own half… it’s a one in a million shot.
“David Marshall had to be in that position because any ball in behind means he’s in the perfect position.
"We can’t lie. It knocked the stuffing out of us but we still created chances. Jamesy had one, Scott McTominay had one and if you get one then then crowd gets a lift but we didn’t manage it and going forward we have to be more clinical."
“We got beat so we’re disappointed. We played pretty well first half without threatening them too much.
“We got in behind them but the first goal was a poor one to lose. It was a brilliant header but we’re extremely disappointed.
“You don’t want to lose a goal from a set play or the second phase of it. And the second one was a brilliant strike but we can do better.
“We played alright and the 2-0 scoreline probably flatters them a wee bit but they found the quality at the right moments and we need to find that in Friday.
“We can either sulk about it or go to Friday with the same attitude and hopefully get a better result.
“We’re here at a major tournament and you need to show your quality. I had a couple of chances, the other boys had chances, and if we want to compete at this level then we need to take those chances and ultimately we were punished for that.
“I wouldn’t say it was a reality check. We played pretty well overall. There were things we can improve on but it’s the first game of the tournament and we have two games to fix what we need to fix.
“It’s important not to sulk too much. We’ll look back on it and then build towards England but we need to do it the hard way now.”
“We played too many long balls for our liking. When we passed it we did quite well but it was hard to break them down.
“We were disappointed with the way the first goal went in following a set piece but I thought we defended pretty well apart from that for the most part of the game.
“They showed real quality for the second goal as we pushed a little bit more for that equaliser.
“It’s not to say we didn’t have chances in the second half. We did and tried to push but we missed a bit of luck and they were clinical.
“Jack hit the bar and Dykesie had a shot which was well saved by the keeper. These little things didn’t go our way but at this level you need to be clinical.
“We need to learn from what happened. It’s a tough one but we need to make a few little tweaks. There were some positive moments and we need to take that through to Friday.
“We’ve got two chances to produce a good performance and get something from them. It’s about analysing what went wrong but not dwelling on it and moving forward quickly.
“The games come fast. We try to focus on game by game and now the first one is out of the way we can look forward to what is a very big occasion and the whole country will be behind us.”
“I saw the goalkeeper off of his line. I checked in the first half in case the situation came up.
“I knew he stayed high so when the ball came I had a quick check where he was standing and it was a nice goal.
"We are so happy we won the game. It’s always hard to play against us because we have a lot of hard working players.
“It’s not easy to play against us but Scotland was a tough opponent and we were ready for their tactics. "
