Manchester United boss Jose Mourinho says there'll be no underestimating Champions League opponents Benfica tonight.
Mourinho is convinced Benfica will be desperate on the night.
He said: "If Benfica lose, they will be left out, if they win, they will stay in the fight, if they draw, they will be fighting for the Europa League and with a Champions League team Benfica would be one of the strongest in the Europa League."
Asked about Benfica's absentees Luisão and André Almeida, Mourinho scoffed.
"I'm missing Zlatan, Pogba, Fellaini, Rojo ... If I could have my players and Benfica have André Almeida and Luisão... but I do not go there."
The United manager also insisted they could win the Champions League this season.
"We can win the Champions League, Porto were not favourites and they won, Inter were not favourites and they won, Real were favourites and they lost three semi-finals. Anything can happen."
Meanwhile, Benfica coach Rui Vitoria still believes they can upset United tonight.
"In football there are difficult games, but we already have enough examples to prove that it is not impossible, it will be a difficult opponent, a difficult game, I would not come if I did not believe it," he said.
"As long as there are points in contention, conformism is not part of my dictionary."
