So what? 30 year old Essien will still be an amazing player. Look at Lampard. Look at Giggs. Age means nothing when you're in that class of player.
You're assuming an injury prone player like Essien will play at the top level for the next 6-8 years? Gotta be kidding. Plus it's Arsenal, we only have 4 players that are 30+ years of age - Sebastien Squillaci (32), Tomas Rosicky (31), Andrei Arshavin (31) and Mikel Arteta (30). Below them there's Bacary Sagna at 29, Andre Santos at 29, and Marouane Chamakh at 28. Look at it like this:
- Squillaci was a completely pointless buy at 30 and is our last choice Centre Back.
- Rosicky is behind Cazorla for the Attacking Midfield spot and is injury prone.
- Arshavin may or may not be sold today but if not he's our 4th choice Winger.
- Santos was another pointless buy and is unreliable defensively.
- Chamakh could be sold or loaned today but if not he's our third choice striker.
- Arteta is our Vice-Captain and easily a first teamer, and the same goes for Sagna.
We don't sign players of that age. It's not what Wenger does.
Anyway, some more deals have been confirmed:
- Charlie Adam, permanent move from Liverpool to Stoke.
- Scott Sinclair, permanent move from Swansea to Man City.
- Danny Rose, on loan from Tottenham to Sunderland for the season.
EDIT - Park Chu-Young, on loan from Arsenal to Celta Vigo for the season.
