Chelsea have endured a dip in form early in the season, with their defence now finding itself in a perilous position.
Xabi Alonso built his reputation on tactical courage, but the system he currently favours appears to be doing more harm than good. With a three-week period ahead, he has an opportunity to make adjustments, and perhaps show the same bravery that defined his rise by switching to a more traditionally English formation, one that could give Chelsea a better balance between defensive solidity and attacking threat.
The 3-4-2-1 shape that once looked innovative from his days at Bayer Leverkusen has become a little leaky and the solution is sitting in plain sight: a switch to a flat 4-2-3-1.
The back three was designed to provide control in possession and defensive security through numbers. In practice, it has often produced the opposite. The wing-backs are being stretched between their attacking and defensive responsibilities, leaving space in wide areas that opponents have increasingly targeted in transition, with more attacks developing from the flanks.
On the turnover, the defensive structure can unravel like saloon doors swinging open at the first sign of pressure, Brentford’s second goal on Friday night offered a particularly clear example.
The problem is compounded when the central defenders are pulled out of position to cover for advancing wing-backs. At the same time, the double pivot in front of them is regularly overloaded and lacks the profile to provide consistent protection in this phase. As a result, the back three can be exposed both out wide and through the centre, with opponents able to attack the space behind the wing-backs or run directly at the exposed central defenders.
What the change brings?
A 4-2-3-1 solves these problems by restoring balance and clarity of responsibility. A flat back four gives each defender a defined zone rather than a rotating set of duties, cutting down on the miscommunication that has led to costly errors. For players like Wesley Fofana, simplicity to his task works while both him and Levi Colwill have excelled in this position in previous seasons.
Full-backs, rather than wing-backs, can push forward with a clearer defensive platform behind them, since two central defenders and two holding midfielders shield the space they vacate and the middle of the pitch, where the goals have been lost.
Those two, likely Reece James and Moises Caicedo when fit, will also provide the platform Alonso's team currently lacks. Instead of a lone pivot being isolated, a double six can split responsibilities, one screening the back four, the other stepping into midfield duels, which should reduce the transitional chaos that has plagued recent performances.
Moving to a 4-2-3-1 would not mean abandoning ambition. A front four of a striker, two wide attackers and a No. 10 can preserve the same attacking intent while providing greater defensive protection behind it. Estevão could start on the right, with Pedro Neto offering an alternative, while Morgan Rogers operates from a narrower position on the left to strengthen his combination with Cole Palmer. João Pedro would lead the line, giving Xabi a clear attacking structure built around his strongest options.
For a manager renowned for his tactical flexibility, reverting to a more conventional and disciplined shape would be a pragmatic adjustment. It would restore greater balance between the lines, offer the defence more protection in transition and, crucially, give the team a more stable platform from which to rediscover its attacking rhythm and form.
