Sagna raps Arsenal over "shock" Van Persie, Song sales
On the departures, Sagna said: "When your two best players go, you ask yourself questions. Fans come up to me in street, and I understand the frustration. Like them I don't understand everything.
"Everyone knew Robin was leaving. But Alex? He's 24 and with three years left on his contract. I still don't understand it. He's a huge loss."
