Despite Switzerland winning their Euro opener against Albania 1-0, boss Vladimir Petkovic was disappointed his side did not make the result more secure.
A goalkeeping error from Etrit Berisha allowed Fabian Schar to head home the winner in only the fifth minute and the first-half sending-off of captain Lorik Cana only added to Albania's problems.
Petkovic wanted his team to press forward, but they could not maintain their early dominance once Albania went down to 10 men.
"We handled the emotion of the occasion better," he said. "We used the nervous energy very positively.
"I think we played a lot better in the first 20 minutes than we did thereafter.
"At first we were dictating the tempo; after that we allowed them to come on to us a bit, we slowed down too much. That happened even when Albania went down to 10 men, though we did miss a lot of opportunities.
"We needed to kill the game off but this isn't all down to our forwards.
"Our defenders and midfielders can contribute in the attacking third, as Schar did with the goal.
"Our aim from the start has been to get through inside two group games. It remains so."
