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.
It is not really about underestimating a team, pep use to win Tottenham Hotspur and if I'm not mistaking that was the same line up he used in there last match and he also know that Tottenham Hotspur is not a team he can win so easily because if you check their statistics very well you will see Tottenham Hotspur has win them more so it is just like History, even though pep used the people you guys feel are the best Tottenham Hotspur will still win them. I was expecting a draw from the match even before they started because I know Tottenham will disturb them but checking Manchester city possession and attempts it was obvious luck was not on their side so that's just the case.
