With Pep noticing the importance of these players and how their absence can seriously affect the teams performance, he is a smart man and will not want to remain limited to them, so that if there is another time like this this season in all the competitions they play were they have to be without Rodri, that their team will still be able to maintain their high performance. This two losses in the premier league does not mean that they cannot still go on to win the premier league again, it just shows that they are not very strong this season.
Manchester City are in the race to win EPL this season, they have declined in performance but all hope are not lost because the club is built on strong foundation by Pep Guardiola. He's not relenting as he's making good efforts to make things better for his team, targeting ultimate priorities for the citizens. Unfortunately the team is about to crumbled due to the absence of key players on the pitch, Kelvin De Bruyne and Rodrigo Hernández Cascante are important for the team, perhaps sooner they will return back to the squad and make positive impact.
