OLd enough that Ray Parlour is still my Fav player to come out of arsenal from the start of me watching the club as a kid, but anyhow ill bite
Mert, was slow and often caught out on the break, along with some poor positioning on many goals,
Koscielny and Vermaelen are our best CB pairing easily and its not even a contest, Merts can warm the bench unless Bartley gets his chance
Santos - was good in attack, hell even great in attack his goal against chelsea was great and clutch, but again for a leftback/defender he didn't do the defending up to a premier league standard, id even go as far to say a championship standard.
i would have much rathered, Filipe Luis or Jose Enrique
i also hate liverpool, but other than not shelling out terrible fees for some over rated english players, we havent exactly hit gold on our transfers lately
Arteta- was always a given he would be class and feel if we had gotten him instead of nasri when we had the chance we would have won the pl in 08/09 or 09/10
Ox - could well be a world class player if he continues
Thomas Eisfeld - could be the steal of the century if continues the way he is
Ryo Miyachi - See OX
As for the rest there is a long way to go
