The giant German believes that judging Arsenal's season on their result next Saturday is 'harsh'.
The Gunners take on Steve Bruce's men at Wembley next season in their season's closing game, as they look to end their nine year search for a trophy.
Even so, it could have been a campaign that was remembered far more fondly. Arsene Wenger’s men had raised expectations after a brilliant start to the season – where they kept pace with the likes of Manchester City, Liverpool and Chelsea to elevate themselves to the top of the league.
However, after injuries to key players, and a drop in performances levels, they have rather meekly surrendered their chance of winning the Premier League and dropped down to fourth position.
Qualifying for the Champions League is not to be sniffed at for The Gunners, but it also isn’t a trophy. And, with that, comes pressure.
Arsenal have not lifted a cup since 2005 and most feel that failure to win in the FA Cup final next Saturday would be hugely disappointing for players, staff and fans of the club.
Mertesacker, though, is of the opinion that defining Arsenal’s success this campaign by next week’s clash at Wembley would be ‘harsh’.
He told the Daily Mail: ‘It wouldn’t be a disaster losing but our expectations are to win the Cup. That is what is in my mind. It’s really about confidence.”
Although the comments may be to relieve some of the pressure off his teammates, with Arsenal going into the game highly fancied, they will surely be of concern to the supporters.
Their nine year thirst for a trophy is one that should have been quenched by now. A club of their size and with their quality should have earned honours and it is not like they haven’t had their chances, either – with Birmingham City’s 2-1 victory over them in the League Cup final being the biggest opportunity they have missed.
It will be a similar feeling for Arsenal if they are to slip up against Hull. Mertesacker may not want his side’s season to all come down to 90 minutes, but in all likelihood it will do.
The imposing German has been one of the North London club's stars this season, being imperious at centre-back and forming a strong partnership with Laurent Koscielny at the heart of the Gunner's defence.
And, even after his comments, he is sure to be determined to maintain this level of performances and lead his side to victory on Saturday.
