One of Unai Emery’s main tasks as new Arsenal manager is to improve the defence.
Towards the end of last season under former boss Arsene Wenger, frailties at the back were evident.
Shkodran Mustafi, in particular, came under criticism from supporters for some shaky performances in the last few games of the campaign.
Emery has already recruited a new right-back in the form of Stephan Lichtsteiner, who has joined the club on a free transfer from Juventus.
Goalkeeper Bernd Leno has also become part of the squad following a switch from Bayer Leverkusen earlier this week.
At centre-back, though, the club are still limited with worthy options, particularly because Laurent Koscielny is expected to be on the sidelines for a significant period of time with injury.
One man who has been linked to Arsenal before has emerged once again in the rumour mill – Chelsea defender David Luiz.
The Brazilian won the Premier League title under manager Antonio Conte in the 2016-17 season, but in the most recent campaign he fell down the pecking order.
Last Thursday, Le10sport reported that the Gunners remain interested in Luiz and had an £18m bid rejected by Chelsea.
It is unclear whether the Gunners will make a fresh attempt to sign the 31-year-old, but the speculation led us to ask you if the Brazilian would be a good signing for the North London outfit.
The majority of fans believe that Luiz could contribute to the effort under Emery.
