Arsenal are preparing an improved offer for Aston Villa midfielder Douglas Luiz, according to David Ornstein of The Athletic.

The lowdown

The Gunners made an opening bid of £20million for Luiz, but it fell short of Villa's asking price (via Jason Burt).

The 24-year-old is into the final year of his contract at Villa Park, and so Mikel Arteta's side know they can sign him on a free transfer next summer if he doesn't pen a new deal.

Arsenal have already strengthened in the midfield of the park this summer with a £31.5million deal for Fabio Vieira, but it seems they're not completely satisfied yet.

Two of their current options - Mohamed Elneny and Thomas Partey - are both struggling with injuries.

The latest

Ornstein took to Twitter to share the update on Luiz, who's 'believed to be keen' to join Arsenal.

He says the Gunners are determined to land the Brazilian before the end of the window, even as Villa stand firm.

"Arsenal going back in with 2nd offer for Aston Villa midfielder Douglas Luiz," he said.

"Opening #AFC approach for Brazil international unsuccessful but they aren’t giving up. #AVFC insist 24yo will not be leaving. Player believed to be keen on move."

As for the timescale, Sky Sports News suggest that it will reach Steven Gerrard's side 'in the next few moments'.

The verdict

Luiz may do all he can to push for a move before 23.00.

Fabrizio Romano even reports that he has agreed personal terms with the North London outfit, suggesting a contract is ready to be signed if the clubs shake hands on a fee.

Right now, though, that looks like a pretty remote prospect, with Miguel Delaney of The Independent reporting that Villa have slapped a £40million price tag on Luiz's head - double Arsenal's original offer.

The gap in valuations may prove to be prohibitive, but things can change quickly on Deadline Day.
