Liverpool manager Jurgen Klopp has admitted that he is still finding it "difficult to accept" the team's defeat in the Europa League final.
The Reds failed to secure the European trophy as they were beaten 3-1 by Sevilla in Basel two months ago.
Klopp's side led the way in the first half thanks to Daniel Sturridge's goal, but they collapsed after the break when Kevin Gameiro scored and Coke nabbed two to secure the title for a third consecutive season.
"Of course I've had a lot of thoughts about this," Klopp told reporters. "It was long ago but it still feels bad.
"After the game I was not in the mood to think too much about the first half but later I did and it was obvious that we'd played a good game in the first half and we could have been in a clearer lead.
"We could have had a penalty for handball, all this stuff that you see afterwards. It's not interesting because it's over but as a human being it's quite difficult to accept all this stuff. Of course you have moments when you still suffer a little bit."
Meanwhile, Liverpool are three games into their pre-season schedule having beaten Tranmere Rovers, Fleetwood Town and Wigan Athletic.
