Current with Manchester City starting eleven against Newcastle United seems Pep Guardiola not prioritize with EFL Cup because starting line up dominance by young player who doesn't get place in Premier League. How ever prioritize or not its become first loss for Manchester City with winning trend in Premier League and UEFA Champion League matches. Little disappointed with Manchester City loss opportunity for winning EFL Cup and giving an opportunity for young player get more minutes in EFL Cup.
I think this is the right decision from Guardiola and I expected it, because you cannot win all tournaments with one squad. The Champions League and the Premier League will be priority tournaments for Guardiola, this is without a doubt, but in all other tournaments players from the bench will play, otherwise the players will not be able to withstand such a busy schedule of games without injuries.
