According to The Athletic, Manchester City is concerned about the right back and winger positions, and Walker is no longer in Guardiola's plan.
TA reported that given Nunes and Rico Lewis are the only two temporary options available, right-back is still a choice for Manchester City. Manchester City is linked to Juventus player Cambiaso and Flamengo player Wesley, but there are not many top players in this position in the transfer market at the moment.
In addition, Manchester City may have another winger, because only Savigno and Doku are pure wingers in the team, and Cherki, Foden, Malmush and B-seat can all play on the wing, but a fast and more direct player can provide Guardiola with more choices.
In terms of players who may leave the team, Walker returns to the team after Milan's loan period, but he is no longer in Guardiola's plan. His contract expires next summer and is expected to leave the team permanently before that. Gallish failed to be included in the Club World Cup roster, but it remains to be seen whether the team that intends to sign him can afford the high transfer fee. McCarthy is joining England in the European Youth Championship, and his future will be decided upon after the team returns to Manchester.
