Why be annoyed with Sagna??
It's these archaic strategies employed by Wenger that has caused him to leave.
Arteta has just critised Arsenal for not offering proper deals for players over 30. It's the same issue we are talking about again here.
Sagna is worthy of a high paycheck - it makes sense on every level to give him one. He is also deserving of a deal longer than 1 year (which is in all probability the main stumbling block here)
Our manager still treats players in their 30's like their career is over but modern sports science just disproves this theory. Players are remaining at the top level for longer than ever thanks to nutrition and improved medical care.
If Sagna goes I'll be annoyed at Wenger. Not Sagna.
