The Gunners defender has reflected on their fine defensive record, and his personal highlight from the 2014/15 campaign.
Arsene Wenger’s side have been the form team in the Premier League in 2015, having gone on a fine run which has seen them keep 11 clean sheets and not concede more than one goal in a game since February.
And full-back Gibbs says it is the increased competition within the Emirates Stadium ranks that has helped the team to secure that impressive record.
“Competition is much higher and that has raised the level,” he said.
“Sometimes in the past we have struggled to put a team out, now we could put two teams out. Everyone has been fit and that pushes each other on. That's been the difference.”
The Gunners appear all set to finish third in the Premier League standings after their fine run of form, meaning they will happily avoid the Champions League play-offs they have faced for several years.
A third-placed finish would, of course, represent an improvement on last season, while they will also be taking on Aston Villa in the FA Cup final to try and retain the trophy they won in 2014 to end a nine-year silverware drought.
On a personal level, though, Gibbs says regaining his place in the England squad has been a personal highlight from the 2014/15 campaign, with injuries having slightly spoiled things for him in the second half of the season.
“Breaking through to the England side again was definitely a highlight,” he added.
"I was involved heavily for club and country in the first four or five months of the season. I haven’t played as much during the second half of the season so really I can only talk about the first half, and that went well for me."
