Pochettino to study incident before deciding whether to challenge Sanchez red
Tottenham boss Mauricio Pochettino will review Davinson Sanchez's red card against Watford before deciding whether to challenge the decision.
Sanchez was dismissed in the 52nd minute for a forearm to Richarlison's face as 10-man Tottenham had to grind out a 1-1 draw at Vicarage Road.
Pochettino refused to be drawn on the incident, but admitted he will weigh up in private whether to launch an appeal against the dismissal.
Any suspension for Sanchez would leave Spurs light in defence, with Toby Alderweireld sidelined until January with hamstring trouble.
Asked if he will appeal the red card, Pochettino said: "I don't know because it's difficult now to see.
"You have a lot of messages on the phone, saying this and that.
"Of course we are going to watch it back now; I think it wasn't intentional but maybe he touched with his arm the face of the player.
"And that's what the referee interpreted.
"No I'm not going to complain, I won't say anything.
"The player said it wasn't his intention, but it's difficult at this point.
"I am not going to say anything about the performance of the referee, in the last four games I think we have first questions about the decisions of the referee.
"And I choose to say nothing about that, what happened happened. We are going to analyse in private."
Christian Kabasele's early header put Watford ahead, before Heung-Min Son's tap-in dragged Tottenham level at the break.
Sanchez's red card forced Tottenham to consolidate rather than go for the jugular, and Eric Dier was fortunate not to concede a penalty for handball with one of the last acts of the match.
The draw leaves Tottenham in sixth place in the Premier League, some 15 points shy of leaders Manchester City.
Spurs have now gone three league games without a win - but boss Pochettino insisted his players will emerge all the stronger for experiencing testing times.
"I am so pleased with our character because it's true the last few games we've disappointed and frustrated with results; we've deserved more," said Pochettino.
"But today the performance, personality and character of the team, playing 40 minutes with 10 men showed really good character.
"In the last few games things are going against us but it's a very good experience for us.
"To live that situation and experience and learn from that for the future is important.
"It's important it's not all easy, you can't always win easy.
"Sometimes tough periods are important, you build your character and you learn a lot from this situation."
Watford boss Marco Silva insisted his side were denied a clear penalty when Dier escaped censure late on, and felt the Hornets could easily have been awarded another spot-kick too.
"It's a penalty," said Silva, of the Dier incident. "I have some doubts about the moment in the box before the counter-attack for the Tottenham goal too.
"Of course I respect the referee's decisions though, this was a tough day for the officials as well as the players."
