It was Wilshere’s first goal in 725 days, and Koscielny admitted he was delighted for the midfielder.
“I’m very happy because Jack lost more than a year with injury,” Koscielny told arsenal.com. “He’s a very good player. He’s young and has a long career in front of him. He played well for the team and it’s good he scored.
“It is very important for a Club like Arsenal to qualify [for the knockout stages].”
