Actually I don't really like this.
Evra's performance this year were average to plain poor.
I understand he's an important guy to have in the squad because of experience, but honestly, performance comes first, always.
He's a disaster in the 352, OK in 442. But he gives us limitations. Any 352 with him is bad. And knowing how conservative and stubborn Italian coaches are (and Italian people in general), even though Allegri is the closest you can call to a "modern" open minded with good common sense Italian coach, he could keep preferring Evra to Sandro, which is appalling and absurd.
We probably just don't want to spend at the position for a backup to Sandro, and there aren't many options. But I don't see Evra as a good player anymore.
