Liverpool tasted their first defeat on home soil for a year and a day following a 1-0 loss to Inter Milan on Tuesday night.
The Reds welcome Milan with a 2-0 lead in the first leg but suffered a 1-0 loss as they advanced to the quarters on a 2-1 aggregate. Lautaro Martinez netted the only goal that separated the two sides as Alexis Sanchez saw a red card for picking two yellows.
Speaking after the encounter, Jurgen Klopp admitted his side found the Italian side a real test despite making it to the last eight of the tournament.
"Inter are a really good side and set up for this kind of games," Klopp said.
"They are really fighters and I’m happy we don’t play this type of team every week."
"Without playing brilliant, we had a lot of clear-cut chances and didn’t use them. They didn’t have many, but they scored a goal."
"Over the two legs, I think it is fine they won one and we are through. That’s a fair assumption. We could have done better against a side that makes life really uncomfortable."
"We lost the game which is obviously not cool, we didn’t come here tonight to lose a home game, but respect to the opponent and we are through. That’s the main target."
On Liverpool performance
"The difficulties we had were pretty close to what I expected," he admitted.
"The opponent caused us problems but if we had used our chances we win this game. We lost a lot of simple balls, which can happen and when the ball was in the air it was like a slapstick with the wind."
"I didn’t like the counter-press, it was not really there. We were around challenges but not in challenges and we didn’t get the momentum, that’s what we were lacking."
Klopp's men will now turn their attention in the Premier League as they travel to take on Brighton at American Express Community Stadium.
