Manchester City have already seen movement both ways in the summer transfer window.
Ilkay Gundogan has left on a free transfer to Barcelona after seven years at the club, and the day after Pep Guardiola lost a No.8 another one walked through the door in Mateo Kovacic. The 29-year-old joins from Chelsea for an initial £25m and has been talked up for the ability to play two different roles in central midfield.
Whether that swap is seen as part of a revolutionary summer or an evolutionary one largely depends on Bernardo Silva. The Portugal international will be allowed to leave again this summer if he brings a suitable bid, but the club have been here before on more than one occasion and such an offer has not been forthcoming.
