First of all, Tottenham weren't the favourites in that game and secondly Manchester city lost due to pep Guardiola's tactical approach which later turned out to be a disaster during the game, the first goal that Manchester city conceded was due to a wrong offside trap from the Manchester city's defensive set up and the second goal came as a result of the blunder committed by the goal keeper and besides I didn't expect players like Doku, Bernardo Silver and Rodri to be on the bench in such a crucial game and that's why I blame the coach's tactics.
You know must times it look like coaches underestimate some team, if not what will those players you mentioned be doing in the bench, pep made a mistake in that match your analysis is right on this, if a team wants to win any match, they have to apply every possible technique for them to win, it seems pep guardiola forgot that the match was eleven eleven against each other, 2 goals scored, he couldn't still recover, so bad, what expensive mistake, may be they will learn later, it is too early for those mistake by Manchester city, they league is just starting therefore, it will be nice if they put theresleves together to put things in other.
