Arda & Vidal were kneejerk election stunts, no two ways about it - throw in the looking transfer ban the board was guilty of doing nothing about to avert and it is an unmitigated disaster. Were it not for the emergence of Roberto being converted into a makeshift RB, we would be quite far up the proverbial creek without a paddle
Truth is, I'm not sure how well we will play overall since so much of Barcelona's attack over the last decade emanated from the right side and that link between Alves & Messi. The more Leo drifts centrally, the less impact we will have on the right thereby shifting a defense's attention to the other 2/3 of the pitch.
Barca will play with a handicap until that right flank is improved and that will also eventually include a RW (Dybala??) with the RB
We will see this recurring sequence during the season, Aleix sliding in late while the attacker skips past him into danger
