.Pep Guardiola insists his Manchester City side are ready to reach the semi-finals of the Champions League for the first time since he joined the club. City lead Dortmund 2-1 in their quarter-final tie ahead of the second leg in Germany on Wednesday. "Tomorrow is an opportunity to prove ourselves. For sure, nobody is going to give it to us. We have to win it, we have to do it. For just being in this position again, nobody's going to say 'here, have a place in the semi-finals' – we have to do it," said Guardiola on the eve of the clash. City have not yet reached the last four of the Champions League since Guardiola joined the club in the summer of 2016.
