Saliba will walk straight into the arsenal starting xi silvestre

I think you may be mistaken!

William Saliba is a talented young defender, but he is still developing and has not yet established himself as a regular starter in the Arsenal first team. While he has shown promise in his appearances for the club, he is not yet a guaranteed starter in the Arsenal starting XI.

Additionally, Lauren Silvestre is not a real person, so it's unlikely that he would be starting for Arsenal!

Arsenal's defense has been a bit of a revolving door in recent seasons, but the team has a solid core of players, including Hector Bellerin, Rob Holding, and Gabriel Magalhaes. The team's manager, Mikel Arteta, has also been experimenting with different formations and lineups, so it's hard to predict with certainty who will start in the next match.

But hey, it's always fun to speculate about team lineups and player performances!
