I pay enough attention to the strategy that is usually used by Pep Guardiola in every team he coaches, he always tries hard to encourage every player as much as possible to avoid incidents that could potentially become injured and that has proven effective because in the season that has passed, we have not seen the man city player seriously injured (different from other arsenal squad or EPL team)
I will say that most of the Manchester City players are mid and good and this is why many of them were able to avoid injuries, and they know how to play games without their opponent hitting them, the main players in the team know how to dodge bullets but even with their too carefulness, De Bruyne got injured at the end and couldn't play even half time in the Champions League, this is strategy helped them and I hope they can use the same tactics next season,
for now pep guardiola is the best coach in the world who is still active but the fight is not over and we cannot predict with certainty whether man icty will continue to be able to defend the UCL title in the following season.
In the world for Treble? I think he needs to win the world cup where players are not borrowed or bought with millions of dollars before you can say such, world cup doesn't need enough funding to lift this, its the raw talent and effort of individuals that win the world cup and those are the places we can praise players, teams and manager, not someone that can turn things around because of money invested.
