You're rewriting history here. Just because we scored one more than the opposition doesn't necessarily mean we scraped past them.
Since Leipzig beat us:
City, cup: draw, non-event
Sheffield Utd away: comfortable win made tricky in the last minutes because of a fluke ricochet off Lindelof
Leeds: battered them
Everton: won comfortably
Leicester: a good team who we were comfortable against but for a silly error in the last minutes
Wolves: a stinker but it almost always is with them
Villa: another good team who we deservedly beat
City in the cup: better team won, though both their goals were set pieces
Watford: meh performance from the reserve team players
Burnley: we were more than good enough for the points and should have by at least two
Liverpool: draw, non-event
Fulham: created more than enough to have won by 3, but poor finishing was the story again. They didn't have a sniff outside of 5 mins in the first half and the last 10 or so mins in the second
Liverpool cup: top performance against a good team
The only games there where you can say we didn't do well in and won were Watford and Wolves. The others were good performances with plenty of effort and endeavour, or against good teams who could give as good as they get.
The problem we have is that we tend to believe our own hype after a good win. That's something that needs to be rectified ASAP, but considering the holes within the team and the squad, and that he's predominantly working with many of the same players who were under Jose, it's something that can and will be rectified in due course.
