They say a good goalkeeper can be worth 12 points over the course of a season, and Arsenal had needed some quality in that area for some time. This time last year they secured the signing of Petr Cech from Chelsea in a deal worth around £10 million according to the Guardian.
He made the move to the Emirates Stadium after losing his spot in the side at Chelsea to Thibaut Courtois - although he was in goal for their League Cup success at Wembley that season, and in other games. But Arsenal could at least offer him some regular game time.
Some stability at last for Arsenal at the back with a little less erratic goalkeeping. A missing piece in the jigsaw that would see Arsenal perhaps go on to lift the Premier League title? That didn't materialise last season as Leicester City shocked the footballing world and romped home, 10 points clear of the Gunners.
His time at the club started off with a Community Shield win over his former employers in August at Wembley, but despite signing a player that had the experience of winning Premier League titles, he alone couldn't help Arsene Wenger's side prevent their familiar failings whenever they are in the mix for the title.
Nevertheless, he proved his worth over the course of the season with his clean sheet record. From 42 appearances in all competitions, he managed to keep 20 shut-outs.
At 34, there are still a couple of good years left in a goalkeeper at the highest level, but it is clear from his first season at the club that Arsenal need a few more additions to challenge for the honours they want to win.
