Donnarumma joined from Paris Saint-Germain on deadline day for 26 million pounds, arriving with a Champions League title and Euro 2020 heroics on his resume. His arrival casts uncertainty over Trafford, who had started City's first three Premier League matches after joining from Burnley in July.

"He is so tall, so huge - he gives us presence," Guardiola said of the Italian international. "He's proven himself in big games - Champions League, Villa Park, Anfield. He will concede goals, that's football, but we'll try to help him."

Guardiola was quick to point out that Donnarumma won't be asked to mirror Ederson's playing style, particularly his renowned distribution. "Gigi has another quality," he said. "I will never ask a player to do something he is uncomfortable with. Ederson was special, but Gigi brings something else."

Despite the shift in personnel, Guardiola emphasized squad rotation will be key throughout the season. "Only one keeper can play, but the season is long - everyone will be involved. They may not believe it, but they will."

The goalkeeping shake-up follows the departure of long-time No.1 Ederson, who was sold to Fenerbahce for 12.1 million pounds after eight trophy-laden years. Guardiola paid tribute to the Brazilian's impact, saying he "helped create a special way for the best decade for this club." Alongside Ederson, other mainstays like Ilkay Gundogan and Manuel Akanji also departed.

Donnarumma's arrival could signal a shift in Guardiola's tactical priorities. With Ederson, City emphasized build-up from the back and sweeping up high defensive lines. In contrast, Donnarumma offers towering shot-stopping ability and dominance in the box - qualities more suited to handling transitions and aerial bombardments, especially against physically aggressive opponents.

Additionally, Trafford remains firmly in Guardiola's long-term vision. At 22, the England U21 international has impressed with his composure and distribution. By keeping both goalkeepers in the rotation, Guardiola could be preparing for varied tactical scenarios across domestic and European competitions, adapting his keeper choice based on the opponent's style of play.
