I've watched some old videos of Barca and is amazing how much space and freedom Messi used to have from the opponent team..now I think he suffers at least 8 fouls per game who are deserving of yellow cards(and mostly remain unpunished). Last year Pedro and Villa knew how to drag players away from him, but in the last month I'm not really seeing it from Alexis, Cuenca or Cesc. Pep should do something about it.
I also had some free time and searched some info about Messi's penalties and he scored:
-14/16=87.5% in the league
-4/5=80% in the CL
-1/5=20% in CdR
-1/1 in the Spanish Supercup
So after seeing Messi convertion rate in CdR, my suggestion to Pep would be to let Cesc or Pedro take the penalties in the Copa from now on.
