Sebastian Kehl had already made his judgment about Chelsea FC before the final act of the London transfer madness.

The behavior of the Blues is "very wild", said the sports director of Borussia Dortmund about the upcoming opponent in the round of 16 of the Champions League.

This had saved the biggest bang for the end of the transfer period: world champion Enzo Fernández comes from Benfica Lisbon to Stamford Bridge - for the record sum of 121 million euros.

"Money doesn't matter there," Kehl said on Sky.

And indeed, Londoners were extremely keen on shopping in winter.

Fernández for 121 million, Ukrainian Michailo Mudryk for up to 100 million euros, talent Noni Madueke for up to 35 million.

Since the takeover of American billionaire Todd Boehly in May, there seems to have been no limit at Stamford Bridge.

More transfers than wins

"We just have to earn our money here in a different way," said Kehl, who was "not able" to implement such transfers with his club.

The "Blues", on the other hand, use a loophole in the financial fair play rules to pull off the XXL deals.

Fernández and Mudryk, for example, were given employment contracts until mid-2031, so that the Londoners can stretch the transfer fees on the balance sheet.

UEFA and FIFA are said to be already planning to close this loophole.

But until then, the “Blues” will do everything financially to end their sporting misery in the Premier League.

The Londoners won their last championship title in 2017, currently the team of team manager Graham Potter is only in tenth place - and in the FA Cup it was already over in round three.

Curiously, this season the Blues have signed more players (16) than they have won in all competitions (12).

“When you are at Chelsea you always have this ambition.

You always want the next trophy.

But the Premier League is getting stronger, every club has more power and can get better players," captain Cesar Azpilicueta said in an interview on the club's website.

glitch around Ziyech

And the Spaniard is right.

The gap between the Premier League and other leagues in Europe is already huge.

All Bundesliga clubs together spent "only" 68.273 million euros in winter - Fernández alone cost almost twice as much.

In total, Premier League clubs have spent £2.8bn (around €3.2bn) this season – a record, of course.

The “Blues” seem to understand more about purchasing than selling.

The Londoners actually wanted to lend the Moroccan World Cup star Hakim Ziyech to Paris St. Germain because of the oversupply on the offensive – but according to media reports they sent the wrong documents to France three times, so that PSG could not register the 29-year-old with the French league association LFP in time and appealed, but was dismissed.

For the Italian European champion Jorginho, the “Blues” raked in a fee of 13.6 million euros from Arsenal FC on Tuesday.

But that's just a drop in the ocean with the additions of Fernández, Mudryk, Madueke, Malo Gusto, Joao Felix, Benoit Badiashile, David Fofana and Andrey Santos for a total of 329.50 million euros.
