MANCHESTER, England (Reuters) -Manchester City manager Pep Guardiola shouldered the blame for his team's shock 2-0 Champions League defeat to Bayer Leverkusen on Tuesday, conceding that his decision to overhaul the starting 11 was a massive misstep.

The City boss made 10 changes from the weekend’s Premier League game, a 2-1 loss at Newcastle United, leaving out key figures such as striker Erling Haaland, who has 14 league goals this season. No other City player has more than one.
