Catalonian Devil,
I know it's partially a case of opinion, but you have to take it realistically not just have empty faith that the other club will strengthen your hopes week after week by losing points. Distractions ? Give me a break. When was the last time under Guardiola that Barca choked and forgot to play their casual football and just get past those jokes of obstacles ? Also, Barca always delivers when they have to, ALWAYS. Even Bojan came up big at some point last season to avoid giving Madrid any chance of catching up with Barcelona.
Barca schedule till the rest of season:
1) Madrid (CdR)
2) Osasuna (H) 16th place
3) Madrid (CL A)
4) Sociedad (A) 12th place
5) Madrid (CL H)
6) Espanyol (H) 8th place
7) Levante (A) 9th place
8) Deportivo (H) 13th place
9) Malaga (A) 18th place
And somewhere in between the last two or after the last one the Champions League final if you get past us.
In NONE of those games you would lose points by any chance, maybe if Espanyol was at home then perhaps (but even this season they got beat so...).
It doesn't take a genius to figure out that the league is lost and it would take probably about 5-8 injuries for Barcelona to drop in football quality enough to give the opposing teams a chance to fight for some result.
