Courtois made a crucial save in Belgium's World Cup win over Panama with the Rode Duivels 1-0 ahead last night.
Afterwards, he laughed: "From Lionel Messi I have learned to keep my legs closed!
"The supporters think that a match against Panama should not be difficult, but this is the World Cup. They are at the World Cup because they deserve it.
"In the first half we were perhaps a bit too structured and we found too little the free man.
"We played well after that goal."
