Barcelona vs Chelsea 3-0 (Aggregate 4-1):5 things we learnt 

#3 Barcelona's bench is still a work in progress

Barcelona lost possession far too easily once Iniesta and Busquets were substituted.

Considering Barcelona's stats last night, where the Catalans only managed to acquire 56% ball possession, it was quite surprising to see Barcelona losing possession far too easily. But one must not forget the fact that Iniesta and Busquets were substituted before the 60-min mark.

After their substitutions, Barcelona found it tough to keep hold of the ball for long and Chelsea took control of the game and created dangerous chances as well. Both Paulinho and Andre Gomez were average, to say the least, and looked out of sorts against the Chelsea midfield.

This goes on to show that Barcelona still require some quality signings to bolster the squad because there are hardly any players, who can act as able substitutes to their terrific playing eleven.
