Chelsea's Failed Kone Transfer: Mbappe's Endorsement and Deadline Day Collapse
Chelsea thought they had their midfield succession plan nailed. Recommendation from a global superstar? Secured. Fee with the selling club? Agreed. Personal terms? Wrapped up.
And then Gian Piero Gasperini said no.
Mbappe’s call and Chelsea’s big swing
In the scramble to replace Fernandez, who was closing in on a British-record move to the Etihad Stadium, Alonso went back to a familiar source. According to Foot Mercato, he picked up the phone to his former Real Madrid player, Kylian Mbappe, before Chelsea made their move for Roma’s Kone.
Mbappe knows Kone better than most. He captains him for France and, by all accounts, did not hold back in his praise. The forward reportedly told Chelsea they were looking at a top-level midfielder, someone ready for the physical and mental demands of the Premier League.
Armed with that endorsement, Chelsea pushed hard. They struck an agreement with Roma worth around €70m (£60m), a fee that sat well above Kone’s initial market valuation but underlined how badly the London club wanted him.
Kone, just 23, had personal terms in place and, as reports framed it, was desperate to make the switch to West London. Everything pointed one way.
Gasperini slams the door
Then came deadline day. And the twist.
Despite the lucrative package and Mbappe’s backing, the move collapsed when Roma boss Gian Piero Gasperini stepped in and blocked the transfer. With the clock ticking, Chelsea suddenly had no time to pivot to an alternative of similar calibre.
It was not the only blow. A separate pursuit of Monaco’s Lamine Camara also unravelled spectacularly, leaving Chelsea’s midfield plans in tatters just as the window slammed shut.
A thin engine room and big injury questions
The consequences are stark. Chelsea’s midfield now looks lighter than Alonso would have hoped heading into the heart of the season.
Romeo Lavia is still wrestling with long-term fitness issues. Moises Caicedo has had his own recent injury problems. That combination strips away options and variety, and it risks forcing Alonso into repeating line-ups and roles he would rather rotate.
For a side with ambitions of challenging on multiple fronts, the middle of the pitch suddenly feels fragile.
Fernandez out, City strengthen again
While Chelsea’s main incoming target never arrived, the headline departure did. Fernandez’s exit was completed in a staggering £125m deal, strengthening a Manchester City squad already overflowing with quality.
His move gives Enzo Maresca yet another technically gifted operator to drop into an already intricate system. Fernandez himself was clear about why he made the jump, saying: “If you look across the squad, City have quality in every area. I want to learn from my new teammates and become a better player.”
Chelsea, meanwhile, are left to replace his influence without the ready-made solution they thought they had in Kone.
Arsenal looming and pressure on Alonso
All of this drops Alonso into a difficult spot ahead of a daunting clash with reigning Premier League champions Arsenal on Sunday.
Chelsea have opened the campaign well, beating Fulham and Brighton, but those wins do not disguise the gap that remains in central areas. Supporters can see the issue. So can opponents. Without Fernandez’s technical control or the powerhouse presence of a signing like Kone, the balance of the side comes under scrutiny against elite opposition.
The Mbappe involvement underlines the type of profile Chelsea are chasing: players with a winner’s mentality, proven at the highest level, capable of dictating big matches. But without a completed transfer, that insight is just background noise. No contract, no solution.
Now the theory gives way to reality. With Arsenal on the horizon and a long season stretching out in front of them, Chelsea must answer a simple question on the pitch: can a midfield this thin really carry a club with such heavy expectations?
