Mikel: Donnarumma was a free agent at the time, why didn t Chelsea sign him?

Former Chelsea midfielder Mikel expressed regret for the club's failure to sign Donnarumma, believing that the Blues missed a good opportunity.
Italy goalkeeper Donnarumma moved from Paris Saint-Germain to Manchester City for 30 million pounds and continued his outstanding performance with his new club. Mikel expressed his confusion as to why Manchester City could easily sign this outstanding goalkeeper.
"Donnaruma was a free agent at the time. Why didn't Chelsea sign him? I don't understand it at all."
The 26-year-old Donnarumma quickly adapted to the new environment in the Premier League. Although some people were worried about his ball-playing skills at the beginning, his performance on the court proved that these worries were unnecessary.
Since joining Manchester City, Donnarumma's save success rate has reached 77.8%, second only to Sunderland goalkeeper Robin Roofs (79.2%). In addition, he kept 4 clean sheets in 8 league appearances.
Although the difference between Donnarumma's expected goals after shooting and the actual number of goals conceded is +0.5, only ranking 10th, considering that he has played 5 more games than teammate James Trafford, this result is still worthy of recognition.
Even if Chelsea had participated in the competition, Donnarumma may eventually choose to join Manchester City. After completing the transfer in September, the Italian star once said: "I am proud to come to Manchester City and satisfied with my choice. I hope to create history here and win as many trophies as possible. This is my goal."
