I genuinely don't get people who make this argument
It utterly ignores the context of what came beforehand, which was the worst run of form in the history of the club
Yes, Lampard picked up 20 points from 18 games, however to put some context around that - split the 18 games in half and Lampard picked up 6 points in his first 9 games, picking up 14 in his 2nd 9 games. Is it really so terrible to suggest that he had a real job on his hands to turn around the form of a club coming off the back of the worst 14 game run in its history?
Eddie Howe, who was lauded for turning Newcastle around, got 7 points from his first 9 games.
I don't see anyone claiming that Lampard is the messiah, but equally I think there's plenty of scope to suggest that he needs to be cut a little bit of slack when you analyse his performance so far.
