But when the team is leaking more goals than anybody except the three in the relegation places, maybe it's time to consider the FB as primarily defensive, even if only temporarily. Even if it does go against a preference for attack, attack, attack!
There's a player in there with the nous to come on ten minutes from time when we're leading by one goal and coming a bit under the cosh, to steady the ship and manage the game out.
Anything else? - not much.
