David luiz is an unbelievable player pablo mari salutes new arsenal centre half partner

I think there may be some confusion here!

David Luiz is a professional footballer who has played for several clubs, including Chelsea, Paris Saint-Germain, and Arsenal. However, he is not a new signing for Arsenal, and he is not a centre half.

Pablo Mari is a Spanish professional footballer who plays as a centre back for Arsenal. He joined the club in January 2020 and has been a regular member of the team since then.

So, it's unlikely that Pablo Mari would be saluting a new Arsenal centre half partner, as he is already a part of the team!
