Manchester: Chelsea manager Antonio Conte called for increased use of video assistance referees (VAR) after a late effort by Alvaro Morata was disallowed by the narrowest of offside decisions, condemning his team to defeat by Manchester United.
"I must be honest, I didn't see the situation, but if you're telling me Alvaro Morata wasn't offside, I think VAR is very important, especially in England," he said.
"There are a lot of moments in the game where there are things to super-check.
"I think the draw was the fair result for this game. But we are talking about a defeat and that's all."
It was a loss that left Chelsea out of the four Champions League places following Tottenham's win earlier on at Crystal Palace.
"We know there is a battle and it will be difficult to find a place in the Champions League," Conte said.
"We had to be more clinical, instead we kept the game open, and the opponent made us pay. Manchester United are a great team, and we must be disappointed, because I repeat today, we could have done better."
Chelsea are now two points behind fourth-placed Spurs and face a difficult next fixture away to leaders Manchester City.
