Paul Merson blasts Rosenior “gamble” after Chelsea limp out to Arsenal

Chelsea’s Carabao Cup exit at the Emirates has sparked fierce criticism, with Paul Merson branding Liam Rosenior’s tactical approach a failed “gamble” after another defeat to Arsenal.

The Blues went into Tuesday night’s semi-final second leg trailing 3-2 from the first leg at Stamford Bridge, but Rosenior’s decision to switch to a five man defence left many stunned — not least those watching from the punditry box. Chelsea kept Arsenal largely quiet for long spells, yet offered almost nothing themselves before being knocked out by a late Kai Havertz winner.

For Merson, the manner of the defeat was as damaging as the result.

Paul Merson did not hide his disbelief while working for Sky Sports at the Emirates Stadium.

“I’m numb. I’m flabbergasted,” Merson said. “I can’t believe what I just watched. This is Chelsea Football Club. They’ve got international players all over the pitch. They’ve got a World Cup winner.”

Chelsea’s cautious set-up initially limited Arsenal’s rhythm, but it came at a cost. The Blues barely threatened throughout the contest, with Cole Palmer and returning winger Estevão Willian only introduced late from the bench.

Former Chelsea forward Kai Havertz ultimately delivered the decisive moment in the dying seconds, sealing a 1-0 win on the night and ending Chelsea’s hopes of reaching Wembley.

Merson reserved his harshest criticism for the lack of ambition shown by Rosenior’s side.

“This is not a bottom-four team,” he continued. “They never had a go. They’ve gone out with an absolute whimper in the semi-final of a big competition.

“If it worked, great. But it hasn’t worked and you can’t gamble like that. Have a go and go out in a blaze of glory. Don’t go out like that.”

The frustration was visible on the pitch, with Wesley Fofana in tears at full-time — an image Merson said summed up the missed opportunity.

Post-match, Chelsea head coach Liam Rosenior pointed to the late fitness failures of captain Reece James and winger Pedro Neto as key factors in shaping his approach.

Merson dismissed that reasoning.

“They are very good players,” he said, “but Bukayo Saka and Martin Ødegaard didn’t play either. They’ll be thinking about this for the rest of their careers.”

In Merson’s view, Chelsea never looked like scoring “in a month of Sundays”, a damning verdict on a night that demanded bravery.

Sky Sports pundit Jamie Redknapp echoed those concerns, stressing that semi-finals demand risk.

“In semi-finals, it’s a completely different thing,” Redknapp said. “You’ve got to throw caution to the wind. Get the ball into the box. Make sure there are no regrets.

“There will be a lot of regrets in that dressing room, thinking we didn’t do enough.”

This was not a collapse — but it was a retreat. Chelsea limited damage without ever forcing Arsenal into discomfort, and that, more than the tactical shape itself, is what has angered observers.

For Rosenior, the criticism will sting. Cup semi-finals are remembered not for control, but for conviction. On this occasion, Chelsea showed too little of it — and Arsenal took full advantage.
