Kevin De Bruyne has made it clear that Belgium will need a top quality performance if they are to progress to the semi-finals of Euro2016.
The Red Devils defeated Hungary 4-0 in Toulouse on Sunday and will next meet Wales in Lille in the quarter-finals on Friday.
Despite an extremely positive showing in the win over the Hungarians, De Bruyne is well aware that to beat the Dragons, he and his teammates will have to be at the top of their game was they were in the second half.
"We played well today. I think we deserved to win, we created a lot of chances," he told UEFA.com.
"The only bad thing is we didn't manage to score a second goal in the first half, but we are happy.
"[Wales are] a very good team, a very difficult team. A fun game to play, I'm looking forward to it.
"Hopefully there will be a lot of Belgian fans in the stadium. That would be fun for us and for the country. We will have to play at the same level as today."
