Liverpool are 3-0 up from the first leg of the quarter-final, but Klopp says City's first-half performance against Manchester United on สมัคร แทง บอล ออนไลน์ Saturday - when they raced into a 2-0 lead - shows his team are not guaranteed to progress to the last four. Ahead of Tuesday night's second leg at สมัคร แทง บอล ออนไลน์ the Etihad, he said: "I saw the game of City vs United at the weekend. It was one of the best first halves I ever saw. It was like a thunderstorm. "Then, in the second half, after the first goal, one team gains rhythm, another team loses rhythm. The game changes. "I cannot tell the boys: 'Boys! Score early!' Well, I can สมัคร แทง บอล ออนไลน์ but I am not sure that it really helps. "We have to think about football: what we have to do, where we have to do it. The boys knew after the (first) game this is half-time. We are in the lead, nothing else." Klopp has a better record against Pep Guardiola than any other coach, having won seven of his 13 meetings with the City manager - and he is targeting an eighth on Tuesday.
