City are likely to offload at least three players to make sure Guardiola has the small squad he craves, according to The Athletic. Walker is on the lookout for a permanent move after spending the latter half of last season on loan at AC Milan, as is Kalvin Phillips following his spell on loan at Ipswich. Jack Grealish is expected to leave too after also being left out of City's Club World Cup squad. James McAtee, who is on England U21 duty with Livramento, is another player who could depart although his future will not be decided until he returns from the tournament.
