Manchester City are ready to begin the post-Pep Guardiola era after 10 years of sparkling football and trophies, but there are plenty of questions yet to be answered.Enzo Maresca is imprinting his style of play: the former Chelsea manager having been identified by City as someone who can bring similar ideals to Guardiola but also put his own stamp on things.The 3-0 defeat against Arsenal in the Community Shield on Sunday alarmed many observers and, though it is too early to judge, there is still some uncertainty around how things will pan out across the first weeks of the new season, at the very least. After all, this is a new manager working with players who have only recently returned from the World Cup, and there is still a lot of transfer business to be done.At boardroom level, City are determined to give Maresca what he needs to ensure the good times continue at the Etihad. This is how things are looking with just three days to go before their Premier League opener against Bournemouth on Sunday.What are the expectations inside the club?City are realistic in the sense that a lot has changed this summer but they do expect the club to challenge and, as Guardiola would put it, to “be there” when the titles are decided.City could win a trophy or they could win nothing, but it will be evident whether they are on the right track or not based on how they compete and how players perform.Nobody will pick up on those vibes more than the executives around the club, who will ultimately decide how things are going.Who have they signed?So far, the only senior player to sign is Elliot Anderson from Nottingham Forest for £116million ($153m). It is a major piece of business and there are high hopes for what the 23-year-old England midfielder can achieve. But a lot more needs to be done.Record signing Elliot Anderson in action against Arsenal in the Community Shield on Sunday (Carl Recine/Getty Images)What is their transfer priority before the window closes?City have to strengthen the midfield after the departure of Rodri to Barcelona, Tijjani Reijnders to Al Qadsiah, and Bernardo Silva to Real Madrid.With Nico Gonzalez, Savinho and Omar Marmoush also possibly leaving, they are working on a late-window squad overhaul.
