When Morgan Rogers opened the scoring after two minutes at the Emirates, fans in Blue would have been right to get carried away with themselves.

But that’s the point. Fans are fans, and players are players. The thrill of being a fan is to get excited, to get carried away, to dream, to live the moments and to be emotional.

This game was a test to see if Chelsea’s cultural changes in the summer were starting to take shape. Unfortunatley, many old habits crept back in from last season.

After opening the scoring away at the current champions inside two minutes, a team that was really ready to challenge for the title would’ve kept their heads and controlled the oncoming flurry of attacks from the opposition.

Anyone watching the match could tell you Arsenal were going to equalise in the oncoming 25 minutes that followed the goal, because instead of staying calm, too many in Blue got a little too excitable and started to engage in unneccesary physical fights or simply just make stupid fouls.

A rash foul from Hato on Saka gave Arsenal a dangerous free kick just after ten minutes. That ended up in the back of net, but was luckily called for offside.

There was a rush of blood to many players heads, like as said, they were excitable children. Wesley Fofana and Joao Pedro were just two of the culprits. Silly, petulant fouls - a yellow in Joao’s case for kicking the ball away.

Havertz eventually equalised from range after an onslaughting twenty minutes where Chelsea could not get hold of the ball and slow down the tempo.

Chelsea’s reaction to their goal will be worrying for Alonso. He was attempting to coach them on the sideline with multiple waves of his arms, seemingly to get them to calm down and manage their heads.

It is one thing to be up for a London derby - yes, you want your players fired up, but there was too many petulant and silly fouls, the Blues simply played into Arsenal's hands.

If Alonso and Chelsea want to get to serious title challengers, they’re going to need to seriously work on managing their emotions, even when things are going their way like today early on.

So far, Alonso’s men have scored in the opening five minutes of all three league matches. This is a new league record and should be appreciated, but they have found it tough to stop games being end to end basketball style matches.

I am not Xabi Alonso, so I cannot give you the exact reasons, but everyone analysing Chelsea can see there is too much gaps in the current 3-4-2-1 setup. The Blues have conceded eight goals in three games.

Rotations from the opposition are causing problems, as are the underlap runs down the Chelsea’s left side. It is too easy for sides to shift Chelsea’s shape around with a few passes.

Moises Caicedo’s return will help plug gaps on the pitch, but captain Reece James must improve his scanning and awareness.

While Reece has great physical and technical attributes, he does not look a good fit defensively off the ball. His lack of awareness to track Martín Odegard single handily cost Chelsea the second goal.

Romeo Lavia was ball watching too, but Reece James failed to track the deep run from Odegard who easily ran off his shoulder.

It was disappointing to see Reece jog back, and then only decide to start sprinting when Odegard was already past him and about to receive the ball through on goal.

Alonso knows it, too. In his post match press conference, he noted that they could have done better on the second goal. While he rightly won’t call out his captain publicly, the evidence on review during the week will be glaringly obvious to all.

It will be interesting in the next few weeks to see what tweaks Alonso makes. This is an incredibly smart manager and Chelsea fans shouldn’t panic long term watching their side defend yet, but there are certainly big red flags that need fixing.
