On Ricciardo's battle with Bottas: "That Williams has such good straight-line speed it is going to be so difficult to keep him behind.
"Bottas is on the option tyre so he has the pace advantage on the rubber and he has the better straight-line speed.
"He will be hoping to get down the inside and make that pass stick into Turn 12."
