Mikel Arteta remains confident Arsenal can complete deals to keep David Luiz, Pablo Mari, Dani Ceballos and Cedric Soares at the club.
Premier League clubs have to sort agreements before midnight on Tuesday with players whose contracts expire on June 30.
The PA news agency understands a deal has been struck with Luiz, who is currently serving a two-match ban following his sending off at Manchester City last week.

The situation becomes less clear where the other players are concerned, with the trio all on loan at the Emirates Stadium.
Dani Ceballos is on a temporary switch from Real Madrid with Pablo Mari, currently sidelined for up to three months with an ankle injury, on loan from Flamengo.
Cedric joined from Southampton in January and is yet to play a game for Arsenal due to a number of injury problems – but Arteta believes all four will remain at the club.

Bernd Leno was then taken off on a stretcher at the loss to Brighton three days later but, having initially feared the worst, the Germany international may be out for up to six weeks.
“Well we thought it was going to be a more significant injury,” Arteta said. “We don’t know the extent of the injury still but at least we know the cruciate ligaments are not damaged.
“That was the biggest fear at the start. He was more positive and in less pain today so that’s good news.”

It was not all good news, however, as Gabriel Martinelli suffered a knee injury in training on Monday and also faces a spell on the sidelines.
“We had some really bad news again yesterday,” added Arteta. “In training in the last action he got hit by another player.
“He’s damaged his knee, the doctors are assessing the extent of the injury but it’s not looking good at all. We don’t know (how long he will be out) but he’s looking at months.”
