I am still shocked by tbe way Torres flopped, I can't make much sense of it. Usually I could blame this on style or something along those lines, but Liverpool's style at the time wasn't that different from Chelsea's and the type of shots and chances he was missing were odd to see from the sniper kind of player he was prior.
I think Sanchez just lost his hunger during the end of his Arsenal stint, there seems to be a theme of doing that in Arsenal with their top earners.
