"Both of these sides are much better on the road than they are at home - United have won all six of their away league games this season," pundit said.
"Leicester, meanwhile, have got half as many points at the King Power Stadium as they have on their travels - nine at home, compared to 18 away.
"The Foxes' latest excellent away result came against Tottenham last weekend and, although there is a lot more to them than just one player, they are set up to get the best out of Jamie Vardy and they play to his strengths.
"An in-form Vardy is hard for anyone to stop, but I look at United and I see a team that is just clicking into gear. I am backing them to make it seven away wins out of seven."
