Jurgen Klopp says his Liverpool team have "a mountain to climb" against Borussia Dortmund on Thursday night.
Liverpool face Klopp's former club at the Westfalenstadion in the Europa League quarter-final first leg on Thursday, and the German insists the Premier League club can secure a positive result despite the contrasting recent fortunes of the two sides.
Thomas Tuchel's Dortmund lie second in the Bundesliga and have made the semi-finals of the German Cup as well as the last eight of the Europa League, while the Reds lie ninth in the Premier League, nine points off a Champions League place with eight matches to play.
"Dortmund are in a better moment in their season but we have had good moments and not had the benefit of it in terms of our league position," Klopp acknowledged.
"If we are not good it will be easy for Dortmund but why should I think about this? We have the highest mountain to climb but it is possible. Let’s play football and talk afterwards."
Liverpool midfielder James Milner says an away goal against Dortmund, who are 16 games unbeaten in all competitions since December, would leave the second leg at Anfield next Thursday finely balanced.
"I don’t think we have to score, but an away goal is always important and helps," he said.
"0-0 would be a good result as well. If we can score, it puts us in a strong position for the second game.
"They’re a top team, but we’ll go out there and try to win the game – that’s the way we play.
"We’ll be positive, try to stop them playing and try to get that away goal. Ultimately, we’re going out there to try and win the game."
