Arsenal have confirmed they are making Pablo Mari's transfer permanent.
£8million transfer option has been the hit as well as tying down David Luiz to a new one-year contract.
Cedric Soares, the Portuguese international who is still yet to kick start a game for the club despite arriving in January, has also signed a "long-term deal", while Dani Ceballos' loan from Real Madrid has been extended till the end of the current season.
The quartet were due to leave the Emirates Stadium on July 1, with their contracts set to expire next week.
All will now remain, most notably Mari, whose loan deal from Flamengo has been made permanent, and ex-Chelsea defender Luiz, who has found himself under fire from fans after his recent red card against Manchester City.
The Brazilian's one-year option had initially not been taken up by the club.
But with both he and Arteta keen for him to remain, a new deal, on slightly reduced terms, has been cut.
“With Pablo we’re all disappointed he got injured at Manchester City. Since Mikel arrived here he was asking for a central defender who was left-footed.
"We were really pleased with Pablo - his behaviour, the way he is training, his mentality and his quality.
"Unfortunately, he has that injury but of course we are really happy to keep him for the future."
Portugal full-back Cedric, part of their Euro 2016-winning side, arrived in North London from Southampton in January on a free transfer.
Injuries mean he is yet to feature for the club since his arrival, but the 28-year-old is understood to have been handed a four-year contract.
It's hoped he will challenge Hector Bellerin for the right-back spot next term.
“Cedric is also going to be an important player," added Edu. "He has been unlucky with the injuries but he is close to being ready and gives us more strength in the right-back position.
"We’re also pleased Dani will finish the season here.
"He is making a good contribution and we look forward to him having a strong finish to the season.”
