It has been reported that midfielder Rodrigo De Paul is battling injury and in doubt for Friday’s clash.
“Our training session was behind closed doors, why are you asking me about De Paul?,” Scaloni told reporters.
“Are you trying to help the Netherlands? Its not good for us when information leaks out into the media, it is all very strange.
“There is one more training session and well see whether Rodrigo and Di Maria are able to play or not.
“The system will also probably depend on how the wingers are doing physically, as the important thing is that whoever plays is at 100 per cent.”
“Were not going to reveal any plans to you - it would be pretty stupid of us to do so,” van Gaal said.
“But it’s not that difficult to come up with an answer as to how to stop him. You might want to block and close the passing lines. I can’t see this creating too much of a hoo-ha.”
Scaloni said La Albiceleste were on alert for any Dutch tactics to manage Messi, including man-marking.
“We might come up with a few tactical differences of our own,” he said.
“We have certain nuances. We can do something different to hurt them and if they decide to man-mark Lionel, we’ll keep it in mind too.”
