Luis Enrique's side lost at Real Sociedad on Saturday night and now lead La Liga by only three points. More worryingly, though, fatigue is setting in just when it matters most.
The Anoeta curse continues. Barcelona had failed to win any of its previous five fixtures away to Real Sociedad in La Liga and suffered another defeat on Saturday night in a tired performance by the team and also Lionel Messi as the season finale approaches.
Messi has looked weary since returning from the recent international break and was guilty of drifting inside for much of the night.
