Arsenal have signed Chelsea centre-back David Luiz in a two year deal deal worth 8m.
The 32-year-old will wear the number 23 shirt.
There was initially concern over this deal getting over the line as three hours after the deadline Luiz's transfer from Chelsea was finally confirmed.
"David has huge experience and I look forward to working with him again," said Arsenal boss Unai Emery.
"He is a well known player and adds to our defensive strength."
