On topic, I refuse to give that Sky article a click so apologies if i
this was mentioned in it. But an interesting 'anatomical' backdrop to Gerrard's slip was his and Rodgers' reported chat in the New Year of 2014. Rodgers highlighted Gerrard's lack of scanning on the field to give himself more time and opportunitues on the ball, hence moving him into a deep role.
You notice Gerrard scanning at least three or four times before he controls the ball and slips, which I'm sure he was doing for the countless other times preceding a glorious ping out right to Glen Johnson or whoever, but it still looks unnecessary. He definitely took his eye off the ball as an indirect result of that chat and the instructions. With the amount of space he was in, one or two scans was enough.
But without his form in the few months beforehand, which had been helped by more scanning, I seriously doubt we'd have been in the driving seat going into that Chelsea game anyway. Suarez was a phenomenon but it's a massive insult to Gerrard and Sturridge in particular calling that side a one man team.
