“I’ve worked closely with Laurent ever since I arrived here and it’s been great to witness his continued progression,” the Arsenal captain told the matchday programme. “He’s really developed his skills in so many areas - his defending, his communication and how he’s handled becoming a key player for this club.

“It’s an absolute joy to watch him play because he has all the ingredients to be a top defender, which he is.

“I’m just proud to be his team-mate and keeping him here was absolutely the best decision the club could have made."
