The head coach of "Manchester City" Josep Guardiola admitted that he is forced to use rotation in the defensive line.
"I would be happy to use the same back four, but we can't handle it. Players cannot cope with being in shape every three days. Maybe other teams can do it, but not us.
Nathan can't do it, the Stones can't. Ruben was injured last season, Emerick is back from a serious injury. That's why it's important to us that everyone can play and everyone can play well.
If you want to fight for all the trophies and claim them at the end of the season, especially with the World Cup in mind, then you need all the players. Otherwise, it will be very difficult," Guardiola was quoted as saying by The Guardian.
