Judging by ths story on ESPN, Sagna could be the next big name to leave Arsenal.
If he doesn't recover fully from his injury, he won't be such a big miss; but on his day, he was the best right back in the Premier League.
For all of Jenkinson's improvment to date, he's still not a patch on old Medusa. But then again, not many right backs are.
Reading between the lines, I get the feeling Sagna was close to Song. That's why I reckon he will follow suit by next summer.
