Roberto Martínez calls Belgium defeat "a needed wake-up call"

Roberto Martínez, Belgium manager, commented on his team form in a Nations League game against Netherlands.

"We played to learn as well and to give players chances. We are using these four games to try and build the players into a team and I got a lot of information today.

It was a needed wake-up call for everyone. We all know we have a lot of work to do. I'll have to look at the selection again and make decisions. I've been with this team for a while now. I need to make sure I don't make mistakes thinking I know some players and automatically they'll be ready for the World Cup."
