As much as I'd love to see us playing with two full-backs bombing down the flanks and taking people on, I think they might be a little pre-occupied with all the defending they'll have to be doing this season. When we come up against the likes of Bale, Hazard and Silva, I'd much rather see an experienced defender with a cool head up against them.
Would be a pretty major overhaul of our style to keep them at home, though; don't expect the fullbacks, whoever they are, to be running roughshod on the flanks, but we relied on their crossing rather heavily and the outlet they provided wide, and that left us exposed on the counter even in the Championship. We're going to need players out there who can provide some support out there while still having the ability to recover...a cool head didn't do us a hell of a lot of good on the occasions when they were caught upfield with fast wingers behind.
