William Saliba has signed a new long-term contract with Arsenal until 2027 and it is certain that one of the young talents that Arsenal possess will be very difficult for any club to touch. We know that in the game towards the end of the season he suffered a serious enough injury so that William Saliba could not strengthen Arsenal's defense during this period and as a result Arsenal also often experienced a decrease in consistency. Mikel Arteta has a lot of confidence in William Saliba as a starter again for next season and it is hoped that his performance will not drop later. William Saliba will also renew his jersey number and he will wear jersey number 2 from next season.
