Speaking to TNT Sports after the match, Van Dijk said: "First, credit to Atalanta, the damage was done last week and we were very poor. They had the perfect game and they deserved to go through. We made it far too difficult for ourselves last week.
"Today was a good game, a great fight and we won but it does not feel like it. It's an improvement but the reality is that we are out and we have to very quickly turn this around and travel to London on Sunday. We all have a responsibility to be ready for it physically and mentally. We are disappointed to be out of the competition as we really wanted to win it.
"We need everyone for the last push and that is the feeling that I am getting now. We tried to [capitalise on the early goal]. We had some opportunities as well. Maybe at times, we wanted to play too quickly and everyone was keen to get the second and eventually then the third. Overall, it was a better game than last week but it wasn't enough."
