Arsenal centre-back David Luiz has agreed a new one-year deal with the north London club.
The 33-year-old's contract was due to expire on 30 June, having joined the Gunners last summer from Chelsea on an initial 12-month deal.
Arsenal have also moved to make the temporary moves of fellow defenders Pablo Mari and Cedric Soares into permanent arrangements, while midfielder Dani Ceballos' loan from Real Madrid has been extended until the end of the 2019-20 season.
Luiz's new agreement comes despite heavy criticism following his display against Manchester City last week, when he was at fault for two goals - conceding the penalty that led to the second - and was sent off.
Mari and Cedric will join on "long-term" deals from Flamengo and Southampton, respectively, with the moves - subject to the completion of regulatory processes - set to be sealed when the transfer window opens next month.
Technical director Edu told the club's website: "I am really happy that we will have these players in our squad for the future. They have been part of the long-term technical plan (head coach) Mikel (Arteta) and I have developed. They bring the right balance to our squad.
"David is a really important player for us. He has played most of our matches this season and has been important for the team. His passing, his communication with the team on and off the pitch. He helps everyone."
Meanwhile, Arteta says he expects to face a German-style side when they take on Southampton in the Premier League tomorrow thanks to the aggressive, pressing game plan implemented by their coach Ralph Hasenhuettl.
Arsenal lost 3-0 to Manchester City in their first match back since the league's resumed from the Covid-19 stoppage before going down 2-1 to Brighton & Hove Albion at the weekend.
"They're a very German side," Arteta told a news conference.
"A manager who has the team into pressing mode, they're really aggressive, really good on the counter-press, really good on the transition... they know what they're doing and they all seem very committed to him. A very dangerous team.
"I know it's a really difficult ground to go to. They have no fear, they go for it and they really believe in what they do and they compete really well."
Austrian Hasenhuettl has helped Southampton overcome a slow start to the campaign, guiding them to victories over Leicester City, Tottenham Hotspur and Chelsea in December and January to earn a new four-year contract earlier this month.
They are 14th in the table and could go level with 10th-placed Arsenal with a win.
Arsenal goalkeeper Bernd Leno, who sustained a moderate ligament sprain to his right knee in the game against Brighton, is expected to return to training in four to six weeks.
