Steve McClaren has demanded his players show more “emotional control” after being given the run around by Swansea’s Jefferson Montero.
Newcastle side were forced to play more than half the game against Swansea City with 10 men after Daryl Janmaat saw red after two first-half yellow cards for fouls on the electric Swans winger.
In the immediate aftermath of the game, McClaren argued that he felt referee Mike Jones could have been more lenient, given the second offence happened 70-yards from his own goal.
But he conceded that Janmaat had given Jones “the opportunity” to give him his marching orders.
McClaren said: “You don’t like to see any booking. You have to try and keep it under control against a big opponent.
“Daryl never did that and he gave the referee, rightly or wrongly, the opportunity to give him a second yellow. If we learn anything, it is emotional control. That has cost us, that is the only lesson we can learn – keeping 11 players on the pitch.”
Janmaat, who will miss this weekend’s match at Manchester United, made a public apology for getting sent off at the Liberty Stadium.
He said: “It was stupid of me and I have to apologise to my teammates, the supporters and everybody, because trying to win a game with ten men is very difficult.”
The Newcastle defence couldn’t cope with Montero, or Andre Ayew on the other flank and McClaren was impressed.
McClaren said: “Montero was very impressive.
“I watched him quite a bit last year and he’s now adding end product to his already good play.
“He’s getting crosses in which are quality and causing problems.
“We knew that would be a danger. Unfortunately he’s done to us what he did to Chelsea last week.”
