The Germany worldwide succeeds Mikel Arteta after the midfielder's contract expired at the end of the season and becomes the 47 different player to lead the north London club.
Of course nobody said anything about buying 20 players, and it's also very easy to draw a parallel between the quality of a performance and the quality of the players you have at the club.
Though experienced and reliable for Arsenal, Gunners fans have still been taken by surprise at Wenger's selection, with many having assumed that Petr Cech or Laurent Koscielny were the most likely candidates to succeed Arteta.
"He is a left-footed player, the quality of his pass is top level and he will help us improve our technical level".
"(In his absence) that's where it will be taken by the assistants.
Arteta also missed much of last season with injuries and struggled to make the first-team even when fit. That will be down a lot to the experienced players'.
Arsenal have named Per Mertesacker as their new club captain despite the former Germany centre-back being in the midst of a lengthy knee injury lay-off.
However, the World Cup victor will have to wait to make his first appearance as the permanent Arsenal captain having been ruled out until the new year with a knee injury.
But Wenger insisted: "If you name a captain and he gets injured you can not say "you will not be captain any more".
The Spaniard's injury problems over the last two seasons have seen several players fill in as temporary captain. If someone is late or on their phone, he is on to them - it doesn't matter who you are'. "He is the one who organises our team dinners, so for me he is a great choice".
"Everyone needs to take responsibility, especially in preseason and show himself from his best side".
'I think we have got the players to do that.
"And in the end, the manager makes his decisions on that front, who's going to play and what are his plans for next season and for the future".
