"You are not sure now that Poland are out of the equation how they will approach the game," he told reporters. "It's impossible to predict what it will do to them - maybe they will relax.
"They've got some big players but we know that if we are at our best, we are capable of getting the right result.
"The magnitude of the game is something we are aware of. The job is half done so we have to finish it off on Tuesday."
