It was a fourth consecutive home game where Sheff Utd have conceded five or more goals.
They have looked well out of their depth in the Premier League and you cannot see that changing between now and the end of the season.
The season has been a harsh lesson for the club and even more testing for their passionate fans.

Sheff Utd allowed the player the time and space to pull the strings for The Gunners all evening.

He takes the ball down brilliantly but tries to beat one player too many instead of getting a shot away.

72. Arsenal's winter break to Dubai seems to have invigorated this team.
They have not looked back since the turn of the year, having their best run of form of the season.
It all remains to be seen how far they get in the Champions League also now as that will surely put pressure on the depth of their squad.
70. This was never going to be one of The Gunners' tricky away fixtures in their remaining games.
Most people are wondering what records there are to be broken now.
Here are some of Arsenal's biggest wins in the club's history.
68. Let's not forget that this Sheff Utd side lost 8-0 at home earlier in the season against Newcastle.
If there is any positive spin on the scoreline, at least it's not their heaviest defeat of the season.
The Blades have now conceded 72 goals this season.
66. The way Martinelli was unable to put any weight on that injury did not look good for Arsenal.

60. Some of these Sheff Utd players will have PTSD after this.
There is still over half an hour remaining, this could be any scoreline at Bramall Lane.
The only thing you would not predict is a goal for the hosts the way this game is panning out.
58. Arsenal just continue to look play through The Blades.
As Havertz pulls the ball down, he lays it off into the path of White.
The defender strikes a left-footed shot into the far corner to make it six.
56. Arsenal continue to come forward looking for more goals.
As it stands this is The Gunners highest ever away scoreline.
They have plenty of time to tear up that record this evening.
