Daryl Janmaat was given the job and he was chasing shadows from the first minute.
Newcastle went down timidly to a 2-0 Barclays Premier League defeat Janmaat was sent off four minutes before half-time for two bookable offences.
Let's be honest, it was only a matter of time because the red car was always going to come out because the Dutchman had no answers to Montero's blistering pace.
The Dutch defender was booked for his second foul on Montero after 17 minutes and, after almost bringing him down again inside the penalty area, he was banished for tugging back the Ecuadorian winger deep inside Swansea's own half.
"You could see their tactics was basically try and kick him (Montero), and full credit to the referee for spotting it straight away," Swansea manager Monk said after the game.
"Quite rightly the player was sent off in the end.
"We talked before the game about Jeff being protected and that's important because it will be a tactic going forward."
