Liverpool boss Jurgen Klopp says Brighton were deserved winners on Saturday.
The Reds were thrashed 3-0 at Falmer stadium.
Klopp later said, "Congratulations to Brighton, they played an outstanding game. I really thought in moments we made it a little bit too easy for them, but in general they played outstanding and we didn't. We tried to help the boys with slightly different organisation. I actually thought it could have worked pretty well; we had moments where it worked well, where put them under pressure, but in all situations when we won the ball we lost the balls in the moment much too easy.
"That's the main problem, so it means we never get this something going. Brighton was better for the whole 90 minutes, but it is 0-0 at half-time, so it is allowed for us as well to play not a good half. We have a kind of result and let's go from there, but then obviously the second half started with the worst possible start.
"Being 1-0 down and the game it was already clear already that one team is ready play a really good game and one team fights with themselves pretty much to get something going. That's then the worst possible start and that's what everybody saw then.
"The problems are the same like last week when we spoke about it: we don't win the key battles on the pitch, the key challenges, and we give the ball away too easily. That's difficult to organise protection for losing balls you should not lose, it is not easy. Fully my responsibility because I had an idea with a different formation and it didn't work out. So, [I am] sorry."
