Liverpool boss Jurgen Klopp mocked Manchester United's tactics for yesterday's 0-0 draw.
Klopp was adamant his side did enough to win a sterile contest with their most bitter rivals but recognised a failure to take chances again proved costly.
"I'm sure if we played like this, you could not do this at Liverpool. Obviously for Man United it is OK. It's quite difficult when a top-class team like Man United has that defensive approach. You're not going to get 20 chances," said Klopp.
"But we had enough, a big one in the first half, and a penalty I feel. We were unlucky."
Klopp was asked in his post-match press conference to expand on what he felt about Mourinho's smothering tactics and the fact United only had one attempt on target. But he replied: "Nice question! If I say, "No" people will say I don't want to win anything.
"If I say, 'Yes' then people are already afraid, so no comment.
"I said it was obvious they made a more defensive approach."
