Poland on a high as Swiss bemoan bad luck

Adam Nawałka, Poland coach
The Swiss are world-class in defence and attack. It's not surprising that when they were losing they chased the game. We had to drop deep to defend and that's why they created chances. But what's most important is that when they scored their goal, you could see the potential of my team. We were able to switch from defence to attack and we took back control.

The first half was great, excellent. We created many chances and scored, but we could have scored more and taken total control. This match sparked a lot of emotions and my players did a great job. We look forward to the next game with confidence. We're prepared for it mentally. We still have reserves [of strength] in our minds and we're releasing them now.

Preparing for this match, we tried to improve our penalties, and we knew they'd be taken in the best possible way. We knew the five players to take them. Emotions were running high so we had to check at the end of extra time if the players still wanted to take them. Everyone had to confirm if that was the case, and all five of them did.

Kamil Grosicki, Poland midfielder
We're very happy to be among the eight best teams in Europe; it really motivates us. Today we had penalty kicks. They must have been a beautiful thing for the fans, but they also meant a lot of stress.

I was standing there and trying not to look. The nerves were horrible. I know what responsibility my team-mates had on their shoulders, but they were as confident as they had been during training. Precise and powerful. Congratulations to them and Łukasz Fabiański.

We keep on developing, we keep on going forward. We want more, but we'll approach it in a calm way. We know how hard this tournament is, how strong the other teams are. Today we are content with what we've got and we'll get ready for the next match.

Vladimir Petković, Switzerland coach
I'm very sad for [Granit Xhaka], but it's not just about him. Switzerland lost and I'm sad about that. The players gave everything and showed what they can do on the pitch. But unfortunately we made mistakes and paid for that. And then it was the lottery of penalties – if you miss one, it can be crucial.

We were too nervous at the start, but then we dominated the game. In the second half, we were the side that deserved to score a second goal. I prefer to stay philosophical. We gave everything, but it's always sad to go out of a tournament and always sad to go out on penalties.

There was nothing special I told Xherdan [Shaqiri at half-time]. There were several attempts to change positions to get players more into the game, and that was proven to work in the second half. [His goal] was instinct and belief, because you have to be convinced when you throw yourself at a ball like that. And you also need a bit of luck, which unfortunately we lacked elsewhere. We did well in these four games. We deserved better, but penalties are like roulette.

Yann Sommer, Switzerland goalkeeper
It's a bitter pill for us to swallow. It was a tough match, in very high temperatures, for more than 120 minutes. We played a good match: we didn't give them much, apart from that one chance they had. In a penalty shoot-out, it's always about who's got the luck.

We're very disappointed; we absolutely wanted to go further. You could clearly see that. We fought well right to the end and had good chances. We would have deserved to go through. I think we were the better team today but that's football.

Maybe we were too nervous at the beginning at the back, too anxious, but we kept on fighting right to the end. Our team gave their all in this tournament. I'm proud of us, our team, and also of our fans. Their support has been incredible.

Xherdan Shaqiri, Switzerland midfielder and man of the match
It was a very nice goal, but in the end it didn't really count for much – it helped us get to the penalty shoot-out, and then we lost. But it was certainly a nice goal, and I'm always proud to score for Switzerland.

We had the better chances to win in the end, to score the second goal, but sadly we didn't do that. And in the penalty shoot-out, Poland had luck on their side. I think we stood up well against a very good Poland side. I think we had them under control, I can't think of one really big chance they had. We had clear chances, were the better team and deserved to go through.
