Guardiola disagreed with Gundogan analysis as his team lost to Juventus. Gundogan felt City were passing the ball too intricately and losing possession in dangerous areas, but the coach felt his team played well and were just unlucky in scoring goals. Guardiola refusal to admit his team's shortcomings has led many to consider him arrogant. The defeat to Juventus was part of a poor period for City, the derby match against Man United will be the next test for City.
Gundogan can be right with his analysis but he is part of Manchester City squad in this match, and as one of Manchester City midfielders, he is responsible for dangerous ball possession loss in the midfield.
Manchester City can control ball very well, have high ball possession, but they lack of speed and surprising attack moments to break their opponent defense. In the match with Juventus, this problem was clearly shown and match turns to super bad for Manchester City after Juventus scoring the first then second goal, it seems to be early ending for Manchester City. With these leading goals, Juventus with their defensive bunker, were able to play more defensive aggressive to defend their goal advantage for a final winning.
Manchester City have those problems in many matches this season from Premier League to Champions League, and with ageing on his body, Kevin De Bruyne seems to lose his magic passes and assists for Manchester City.
