Torres was given his marching orders in the 81st minute after he was adjudged to have jumped into Vertonghen whilst contesting the ball.
TV replays showed there was no contact between the two players, and in the post-match interview Mourinho was bemused at how Vertonghen was lying on the floor holding his head.
As Torres walked off, Mourinho put his arm around the striker and whispered some words into his ear. What he said wasn't picked up by the TV microphones, but French journalist Julien Laurens covering the game heard a snippet.
Here's what he tweeted after the incident:
Torres sent off. Mourinho just told him: "You should have stayed down" as he walked off the pitch.— Julien Laurens (@LaurensJulien) September 28, 2013
Commenting on the incident post-match, Tottenham manager Andre Villas-Boas said the referee had a tough decision to make:
"It was difficult for the referee to judge. I don't think Fernando went in nasty to deserve a sending off. The referee decided both players went in in an aggressive way, but it was probably an unfair sending off."
What do you make of what Mourinho reportedly said to Torres? Is he right to tell his player off for being honest in the circumstances?
