Very difficult to pick just 5, and it depends on whether you think of 'talented' or 'influential'. Raw talent, disregarding what the players may or may not have won for us, I'd probably pick Henry, Bergkamp, Vieira, Campbell and Pires.
I love Özil, but so far I'd still have Pires ahead of him because Pires was overall a bigger threat due to as well as being able to hurt opposition with his sublime passing, he was also a consistent scorer. Alexis is a great player, but he has nothing on either Pires or Özil IMO.
