Calling a routine, or maybe not so a routine victory over Sevilla as one of the 'Most Valuable' could be a bit far fetched. But in the small scheme of things, this victory mattered much more than everyone realizes. Just imagine failing to win that match, what could be the impact of the same on Barca's important fixture week.
Losing Messi for three weeks is a huge blow, but had it been coupled with another failure to win, the entire preparation for a midweek encounter with Inter Milan would have gone for a toss. That match is very much important in the grand scheme of the group, a victory there would more or less secure the top spot for FC Barcelona.
