The Gunners boss Arteta is excited to work with Saliba.
Arteta insists Saliba will need time to adapt to his new surroundings at the Emirates Stadium.
Mikel Arteta has urged Arsenal fans to be patient with William Saliba as he prepares to join the Gunners ahead of next season. The 19-year-old, who signed for the north London club from Saint Etienne last summer for a reported fee of £27m, spent the 2019/20 season on loan with his boyhood club. All in all, the Spaniard says he is “excited to work with” Saliba, adding that he will need time to adjust to English football. "I am excited to work with him, but I am worried about the expectations because I know how difficult it is to play as a central defender in this country," said Arteta. “It is one of the most complicated positions here. The step is really, really big. William had a really positive season last year, but he has had a really difficult one this year with injuries. “We know where the potential is, but to fulfil that potential every three days at the highest level is a different task.”
