DAVID ROGER from Glasgow asked Derek:
Can Belgium win the World Cup?
I thought the Belgium game against the United States was the best I have seen at this World Cup.
I am on holiday in Spain just now and I watched it with several hundred other guests in the hotel. I have never seen so many people so excited by a game.
I don't know if playing 120 minutes will have an impact on them. But I think they showed what a good side they were in their last 16 match.
Everybody has been raving about other more fashionable nations at these finals. But Belgium are a good side and it would be foolish to rule them out as contenders.
