Switzerland coach Koebi Kuhn said he was proud of his players as they battled to a 0-0 draw against Croatia.
The Swiss had Johann Vogel sent off for two yellow cards but his team-mates held on for a point.
"I am very proud of the team, it was a good performance for 90 minutes and very good in the second half with 10 men," said Kuhn.
"It was very hard but it is too early to say what this result means. We have to wait until we have seen more games."
Switzerland's final game in Group B is against England, and Kuhn said: "We have a good record against England but we know we have to improve up front.
"We had some chances and at this level you have to take them."
Kuhn added that he felt Vogel's sending-off - after he kicked the ball away having already been booked - was harsh.
"Vogel thought the decision of the referee was for our team and that he would
continue the game," said Kuhn.
"But unfortunately, the referee decided - as he
did so often - that it was not for our team but the other."
