David Luiz: Arsenal defender signs one-year deal with Gunners, who give contracts to Pablo Mari, Cedric Soares & Dani Ceballos

Luiz was out-of-contract at the end of June and, although he endured a horror show in Arsenal's 3-0 defeat at Man City last week, Mikel Arteta had backed him to get a new deal at the club.

The 33-year-old Brazilian defender has been prone to errors and red cards during his time at the Emirates, but Arteta has enough faith in him to keep him around for another 12 months.

Meanwhile, the Gunners will make loan moves for Mari and Soares, from Flamengo and Southampton respectively, into "long term" permanent deals once the next transfer window opens.

Arsenal, who sit in tenth in the Premier League after successive defeats in the restart, have also extened Ceballos' loan move from Real Madrid until the end of the season.
