I had the pleasure of watching the Brazil game last night (corporate tickets!), Rafael looked pretty good, was well chuffed when he scored. Otherwise he played quite defensively for the most part I thought, kept things simple and just played the ball through to Neymar and Oscar (who looked good).
For me, he should be our starting RB when fit, simple as. Smalling is a CB and that's where we should be trying to play him, as for Jones, he is becoming a bit of a JOS
On the Fabio topic I agree he should have played more last season. Evra was a liability at times and it would have done no harm to give Fabio more game time, which is what he clearly needs.
