Chelsea manager Liam Rosenior took charge of his first game at Stamford Bridge, losing 3-2 to Arsenal in the first leg of their League Cup semi-final last night.
The Blues were the architects of their own downfall as two mistakes from Robert Sanchez and a fine Martin Zubimendi goal gave the Gunners an advantage for the second leg.
While Chelsea showed some bravery, Rosenior’s set-up had apparent weaknesses that Arsenal easily exploited.
Chelsea’s pressing structure left a lot to be desired. The intention to press high was clear, but the execution was disjointed.
They often jumped out to engage the centre-backs without adequate support behind the first line, leaving vast spaces for the Gunners to play through.
The press lacked cohesion and timing, with individuals stepping forward rather than the unit moving together, making it easy for Arsenal to bypass the initial pressure.
That structural flaw quickly snowballed into a bigger problem. Chelsea were far too easy to play through.
Arsenal sliced and diced their way through the middle of the pitch with alarming regularity, rarely needing to force the issue or go long.
Zubimendi, Declan Rice and Martin Odegaard repeatedly found pockets of space between Chelsea’s lines.
They were receiving on the half-turn and driving at a backline that was constantly retreating.
The midfield gaps were jarring to watch, particularly when Rosenior’s side lost their shape after a failed press.
Arsenal repeatedly pulled Chelsea’s midfield out of position. Once one player stepped out, the domino effect followed, opening corridors to the uncertain Chelsea rearguard.
It created a stretched, broken block that offered little resistance and invited pressure onto a defence already lacking protection.
This was not a one-off. Chelsea’s 5-1 win over Charlton Athletic flattered their actual performance, as the same structural issues proved to be a major problem.
For all the attacking flashes the Blues showed, their off-ball structure told the real story. Until Rosenior tightens that framework, his team will struggle.
