The 'new' Arsenal

Looking at Sunday's team, I was struck by the lack of longevity:

Mannone – not played much

Jenkinson – 2nd season

Vermaelen- 3rd

Mertesacker – 2nd

Gibbs

Arteta- 2nd

Diaby – like Rosicky, so often injured, that he’s a 'new signing‘ each season

Cazorla – 1st

Gervinho – 2nd

Podolski – 1st

Giroud – 1st

I guess the short time at Arsenal is balance by the age and experience of the players who have come in.
