Barcelona sports chief Andoni Zubizarreta admits they miss something in the air after their summer departures.
Zubi admitted that the departures of Yaya Toure, Rafael Marquez, Thierry Henry and Zlatan Ibrahimovic in the summer has removed the aerial threat from the team.
"When you look at the team poster, we have clearly lost height. But defensively, it's a good side, and it's not as if we're an English team, who are always physically more powerful.
"We might pay for that in some games, but strategic defending has nothing to do with height."
He also praised Javier Mascherano's commitment to sign for Barcelona after accepting a pay-cut to join the Blaugrana from Liverpool.
"It's the first time I've seen it. Then again, at Athletic some players would sign their contracts and not even bother reading what it said.
But professional football's not easy. I was surprised from the moment we contacted the player, but his intention was always to come to Barca."
