McClaren dismissed Monk's claim that Newcastle had sought to stop Montero by targeting him for rough treatment, with the former England manager insisting his team do not play that way.
"We haven't got a team capable of doing that and I don't think the game represents that now," said McClaren.
"Our team is a football team, not kickers, so I would dispute that.
"As always, you make your presence known to your opponent, which we did, but there was one tackle too many.
"I thought the red card was harsh, he was a long way from goal and it was a little tug. I thought the referee could have been lenient."
