"They're at our level, without any doubt, because of the way they press and attack. They have a magnificent coach in Vladimir Petkovic and they'll cause us a lot of problems."


The teams met twice in the Nations League last year, Spain winning 1-0 in Madrid but only scraping a 1-1 draw in the away game thanks to an 89th-minute equaliser from Gerard Moreno after the Swiss were reduced to 10 men.

"We were superior to them in Madrid even though the scoreline didn't reflect that and they only created one chance all game. But both games were tough because they press you high in your own half, run very hard and I don't expect anything different tomorrow," Luis Enrique said.

"In this tournament they've been a reflection of what they are, which is a very hard team to beat who can go all the way, just like us."

While Spain have enjoyed far greater success than Switzerland and won a hat-trick of international trophies between 2008 and 2012, they also achieved a major milestone in beating Croatia 5-3 after extra-time on Monday to win their first major tournament knockout game since the Euro 2012 final.

Like Switzerland, Spain were forced into extra-time in their last fixture but the coach was not worried about his players feeling tired.

"The physical impact won't affect us, we have great fitness coaches and the data we have seen is incredible," he said.

"The mental factor is just as important and if you are convinced about what you're doing and feel good in the head, you can fly out on the pitch. I think we're in top shape physically."
