The match against Leverkusen is Guardiola's 100th game in charge of City in the Champions League. "I realise I'm getting old, every weekend it's milestones and milestones," he said. "It's quite good, it means that every season we have been there. We're the only team in England that have been there the last 10 years every season and hopefully we'll be there next year. It's a huge competition, so nice, so special for the players, they love it, managers and everyone. To challenge yourself against the best teams in Europe is incredible, a huge experience. For the club in terms of reputation, financial issues it's massively important."
