That's essentially how I saw it, but think JRod deserved a 7.
Gaston was decent - provided the real incision in the first half and was always wanting the ball. Less effective second half.
On his walking off: Lallana was already and prepped to come on for him, Gaston wandered over to the technical area, and just kept going.....guess he thought the substitution was happening, but it was a couple of minutes until there was a break in play.
Our defence was ****, and there was little cohesion to our pressing. Won though, so won't complain too much.
