Chelsea defender David Luiz is set to join Arsenal before the transfer window deadline, it was gathered.

Luiz is expected to complete his move on the morning of Transfer Deadline Day.

The 32-year-old Blues centre-back trained away from the rest of Frank Lampard’s squad on Wednesday.

Arsenal head coach Unai Emery told Sky Sports News he wants to sign a centre-back before Thursday’s deadline and it is understood Luiz is on his shortlist, although there has been no formal bid for him at this stage.

“If we can on the last day, we will try to sign another centre-back, but one who has the capacity to help us,” said Emery.

“We have a lot of defensive players. Maybe, it is different when Laurent Koscielny tells us he wanted to leave.

“We tried to sign some important, expensive players for our defence. But when we can’t do that, the second line players don’t really convince us to sign them.”

Chelsea is reluctant to let Luiz – who signed a two-year contract extension in May – go to Arsenal, due to their ban on registering new players until next summer.
