Arsenal manager Arsene Wenger says the experience of Laurent Koscielny in defence was instrumental in keeping a clean sheet against Leicester City at the King Power Stadium on Saturday.
The defender made his return to the Gunners first-team after a busy Euros with France, reports the Arsenal website.
The 66-year-old manager says his presence at the back was the difference in his side’s goalless draw against the defending Premier League champions.
‘We look a different team straight away and he gave us stability against a team that attacks very well,’ Wenger said.
‘I saw that we were a bit too young [in defence] and I have no real solution at central defence at the moment. In fairness, he had a big back problem yesterday when he came out of the training.
‘We came with 19 players and this morning we decided that he could play and I think it saved us this point.’
Last season, Koscielny featured a total of 44 times for his side while scoring four goals in all competitions. He also helped the Gunners to a second place finish in the Premier League.
Arsenal will now travel to Vicarage Road when they take on Watford in the Premier League on Saturday.
Kick-off has been set for 16:00.
