Chelsea goalkeeper Thibaut Courtois has warned his Belgium teammates not to underestimate Wales in their Euro qualifier.
Courtois claimed that Wales, spearheaded by Gareth Bale, would crush his country if they repeat the performance they put in for their friendly win over Iceland.
"I don't think we should be happy with the 3-1 victory," he said. "We created a lot of chances, but we also gave away a lot of space.
"Some players weren't doing their defensive job. If we play like this on Sunday against Wales, we'll get crushed.
"That's what I told the manager straight after the game. I told him who didn't do their job. I know it was only a friendly, but the guys should always be willing to run. If not, then they should be put on the bench."
