I don't mind a little of this sit-back approach for a bit as we settle into the match, as long as we're playing good lines and defending well. The match is all about shifts in momentum, and I wouldn't mind letting Roma get overexcited in the early stages... only to hold them and then switch advantage later on.
That's the kind of match discipline I'd like to see for a change against a quality team vs. scoring too soon or conceding early.
