Defender signing completed
Arsenal, Latest news update:
Arsenal will unveil Lorient centre-half Laurent Koscielny on Thursday afternoon after reports in France claimed a deal had been done.
Arsene Wenger has been desperate to add to his back line all summer and the deal for the 24-year-old has been expected all summer but it has taken some time to go through.
The deal is said to be worth £8.5m for the player who is thought to have already been training with his new team-mates at the club's complex in London.
Lorient said on Tuesday that the deal would be ratified within "hours or days," with the club's general director Serge Areguian saying the hold-up was due to "administrative details to be validated."
