Nemanja Matic believes Jose Mourinho has prepared United for their clash with Liverpool
The Portuguese manager has been showing his side footage of the Reds and areas they can exploit, fine details which Matic thinks could be crucial.
Matic said: "We have prepared very well. The manager got some videos for us to see what [Liverpool] have in their team and how we can stop them, so I'm sure we will be ready for them.
"It's like every game - we have to be focused for the 90 minutes, we have to take care of the small details, because they can be dangerous.
"It's very important to know at every stage of the game what we have to do. Every small mistake they can punish you, so our concentration is very important, but, of course, we have to use our quality to score some goals as well.
"They always want to score goals in the first 10-15 minutes. We have to be ready for that, and we have to be very aggressive in the same way they try to be. I've played [at Anfield] a few times and they always try to be like that, but we have the quality to stop them. It's a big derby, it’s a special game for our fans and for their fans, so, I'm sure our fans will enjoy it and support us for the whole 90 minutes and we will try to make them happy, of course."
