See you have to understand football beyond the commentary and the stats. Chelsea created opportunities to score, they did not score, as I said they did not execute the final pass (the shot) therefore no stats. Stats don't measure the means, just the ends.
We were out shot, yes, but when did those shot come? After the sending off. It's funny you can understand that in Liverpool game but not ours. Funny.....hmmm. You using total shots, I am dealing with shots on goal. At half time Liverpool had 2, from 2 PKs. Man United had 1. Your shots on target in the run of play came after Vidic was sent off.
Dude Chelsea was all over Villa and for a long time Villa was parked in front their goal. Their back line stayed put throughout the game. Just like Liverpool had Man United in bits, but the stats don't reflect that.
See when you are coaching a team, stats is only part of your decision making. A major part of the decision making is the eye test. See Chelsea heat map could say we expend lots of energy in our defensive 1/3, but what it may not tell you is that it came after being down a man.
I'll use an example, the US U17 men's team vs Honduras WCQ. The USA lost 3-1 to Honduras first time ever and did not qualify for the WC. The Pro Zone stats told them that the AM was the player who gave up possession the most, what the stats did not show was that he was the player who was attempting to play the entry pass or take players on to create opportunities (the best player out there). The best player of the game according to ProZone for the US, only played the 1st half.
Stats is great and all, but you have to use stats in contrast or in comparisons to what you see in the game. Ask AVB how those stats working out for him.
