Chelsea's Tactical Experiment: Right-Backs in Midfield and Missing Caicedo
Chelsea spent £349m in the summer and still ended a statement game at Emirates Stadium with two converted right-backs side by side in midfield.
On the day they wanted to show they were closing the gap on the champions, that image told its own story.
Right-backs in the middle, points on the line
Reece James, once again pushed into midfield, had largely justified Xabi Alonso’s bold belief that he can become one of the best in the world in that role. He was composed, aggressive, involved.
Then he switched off.
James failed to track Martin Odegaard’s run and the Arsenal captain punished him, ghosting into space to score the winner in a 2-1 defeat that handed Alonso his first loss as Chelsea manager. One lapse, one decisive moment.
By the final whistle, Malo Gusto – another natural right-back – was alongside James in the centre of the pitch. Gusto had come on for Romeo Lavia, a midfielder by trade. Chelsea, who do not have European football and have fewer fixtures to juggle, finished away to the champions with two full-backs running their engine room.
For former England international Ashley Young, watching on for BBC Sport, that picture was impossible to ignore.
“The worry is you're finishing a game against the champions, and you've got two right-backs in midfield,” he said. “The front line are going to send fear throughout the league but behind that you see the midfield and they're playing right-backs there.”
Young’s verdict cut deeper as he picked at the tactical seams. Chelsea sat deep, packed bodies behind the ball, but still allowed Arsenal to find gaps.
“Teams will be seeing the game today, seeing that Chelsea will sit in there and get men behind the ball, but there's still spaces through the lines, and Arsenal found that out,” he said. “Chelsea are giving up a lot of possession and they're playing counter-attacking football. Today there was probably only once with Pedro Neto down the right side when they capitalised on the counter.”
The plan, such as it was, never truly bit.
Life without Caicedo
Strip everything back and the central problem is simple: Moises Caicedo is missing.
The Ecuador international, Chelsea’s midfield anchor and ever-present in recent years, is out with an unspecified injury. He broke down just 11 minutes into a substitute appearance against Brighton last week and now faces an uncertain spell on the sidelines.
For Alonso, this is unfamiliar territory. Across the previous three seasons, Caicedo had missed only two games through a minor knock and illness. Managers build around that kind of reliability. Suddenly, the cornerstone is gone.
“Not longer term, but it is about assessing the risk,” Alonso said when asked about Caicedo. “Probably last week we brought him back too early and I don't want to make the same mistake again.”
Chelsea insist this is caution, not crisis. But the timing stings.
The club spent deadline day scouring the market for central midfielders. Monaco pulled out of a £47m deal for Lamine Camara at the last moment, leaving Stamford Bridge officials furious. Bids of up to £64m for Bournemouth’s Alex Scott went nowhere. A move for France international Manu Kone collapsed when Roma head coach Gian Piero Gasperini blocked it.
Chelsea’s line is that Camara was an opportunistic move, not a necessity. They maintain they are happy with their business and trust the players they have.
That stance looks braver when you remember what else happened on deadline day: Enzo Fernandez left for Manchester City in a joint British-record £125m deal. No direct replacement arrived.
Now Caicedo is out. Jordan Henderson is still recovering from a broken arm suffered in a freak fall over an advertising hoarding while he was an unused substitute at the World Cup. And natural midfielder Valentin Barco, signed from Strasbourg, has been overlooked in all three Premier League games so far, with Alonso preferring Gusto in that hybrid role.
Possession sacrificed, questions growing
The numbers underline how drastic the reshuffle has been.
With Gusto starting in midfield, Chelsea saw just 25.6% of the ball in last weekend’s 4-3 win over Brighton – their lowest possession figure since records began in 2003-04. They won, but they did it by leaning heavily on their forwards and living off scraps.
Alonso argued before the Arsenal game that, in a season without midweek European commitments, five fit midfielders would be enough. On paper, if Caicedo’s injury is minor and the rest stay healthy, that logic holds.
Reality is already testing it.
Chelsea have conceded seven goals in their first three league matches. “We want to be tighter,” Alonso admitted. The back line is exposed, the midfield balance fragile, and the tactical trade-off – solidity for counter-attacking threat – is only paying off in flashes.
The attack is doing its part. Morgan Rogers, the club-record signing, struck again inside two minutes at Emirates, becoming the first Chelsea player to score or assist in each of the club’s opening three Premier League games of a season since Eden Hazard in 2018-19. Cole Palmer looks sharp and inventive. Joao Pedro has started as if goals are a habit he has no intention of breaking.
That trio has carried Chelsea’s early-season spark. They have also masked, to a degree, the structural issues behind them.
Arsenal still the bar to clear
Strip away the result and there was plenty in Chelsea’s display to encourage Alonso. This was arguably one of their better showings in a grim recent run against Arsenal, stretching to 10 matches without a win.
They went to Emirates to compete, not just survive. They led, they pressed in moments, they stayed in the game. But the champions had more depth, more control, more answers from the bench. Mikel Arteta’s substitutes tilted the contest, while Chelsea’s options could not change its rhythm.
Alonso, though, refused to sound deflated.
“We came to win. We knew that we were not that far, but it went their way,” he said. “It hurts, [we're] disappointed for sure. But this is the first defeat, this is going to be a long way and it doesn't have a big impact in our mood and in our mindset.”
The table offers a harsher reminder. Chelsea finished 10th last season, 33 points behind Arsenal. One busy summer, even one costing £349m, does not erase that gap overnight.
Arsenal remain the benchmark in London and across the league. Chelsea may have beaten them to Rogers’ signature, but in almost every other measure of where a squad stands, the champions are still out in front.
Alonso has called this summer “phase one”. The squad overhaul is not finished, the project still in its early chapters. Yet the failure to land a central midfielder on deadline day has already been exposed as a potential fault line.
If Caicedo returns quickly and restores order in front of the defence, this might be remembered as a brief wobble, a tactical experiment born of necessity. If he doesn’t, or if the same issues persist even with him back, the question will sharpen:
Did Chelsea misjudge the heart of their team, and will they have to pay for it again when the window opens in January?
