John Terry analysis unpacks Chelsea's derby defeat against Arsenal

The London derby at the Emirates Stadium ended in a painful 2-1 defeat for Chelsea. The Blues got off to a flying start with Morgan Rogers rifling home just two minutes in. However, they couldn't maintain their lead. Kai Havertz levelled the score on the 25th minute, and after the break, Martin Odegaard secured a comeback victory for Arsenal, helping Mikel Arteta's side continue their perfect start to the Premier League.

Chelsea legend and former captain John Terry has issued a detailed analysis on his personal YouTube channel, dissecting the key moments from the game. The former defender pointed out a troubling trend: the German forward has been finding the net against his former club with alarming regularity since leaving Stamford Bridge.

Terry highlighted a series of positional errors leading up to Emiliano Martinez's goal.

Positional failure: Havertz finds space

According to Terry, the breakdown begun as soon as the ball was switched to the flank:

I want to break down Havertz's first goal in detail. It seems he is scoring against us constantly since leaving the club, but I want to get into the specifics. The issues began with the pass moving out wide. I'm sure Emiliano Martinez is frustrated as he’d want to play it more confidently and clear the ball securely. He made several excellent saves during the match, but he won’t be happy with that moment.

However, for me, the key moment happened before the ball even reached Havertz. The pass goes to the flank, into this open area. That’s when Havertz appears. Ideally, the forward is looking to get onto his stronger left foot. As soon as the ball goes wide, Reece James should have immediately closed that angle off, while the central midfielders needed to drop deeper.

Terry emphasised that the passivity in the defensive line robbed the team of compactness. If James had shifted over, Havertz would have been forced wide toward his weaker right foot or to pass back. Instead, the gap between the lines allowed the German to move centrally unimpeded and prepare for a shot.

Arsenal's compactness as a model for the Blues

In analysing Chelsea's tactical issues, John Terry pointed to Arsenal's organisation under Mikel Arteta:

In the coming months, you're going to hear me talk about the 'number of players behind the ball' quite a lot. It’s crucial because it forces the opponent to go around your defensive structure. Arsenal do this brilliantly. When they lose possession, they immediately pull numbers behind the ball. Breaking through them or finding passing lanes becomes incredibly difficult. We, on the other hand, willingly opened up space for them.

Maxence Lacroix's misfortune and Emiliano Martinez's frustration

The final phase of Havertz's shot evoked professional sympathy from Terry for central defender Maxence Lacroix:

I've had this happen to me numerous times in my career – there's nothing more frustrating for a centre-back. You do everything right, and Lacroix was in the correct position, but as he stretches to tackle, the ball sneaks right through his legs.

At the same moment, Emiliano Martinez shifts to the side to better view Havertz's left-footed effort, but the ball sneaks through Lacroix’s legs and finds the bottom corner. It's happened to me countless times. In such moments, the defender can't do anything about it. Still, I reiterate, Martinez did get a hand to it, so he'll definitely be blaming himself.

In conclusion, Terry noted that the conceded goal exposed a systemic issue that the coaching staff must address swiftly:

Tracking back, keeping as many players behind the ball as possible, and maintaining clear sight of the game are fundamental requirements. We desperately need to improve our reliability and impose stricter discipline in defensive situations.
