The competition to be the biggest regret of Chelsea's is a hot one. Dominated by the Mohammed Salah, Kevin De Bruynes and Romelu Lukaku of a previous world, there is a new wave of players that weren't just sold for cheap. They were produced and let go too soon.
Often spoken about is Declan Rice, but joining that list could also be Tino Livramento, Marc Guehi and possibly Levi Colwill, depending on how Thomas Tuchel plays next summer. This is all without considering the players that have played for Chelsea more recently but gone on to be sold.
There's a new competitor now, though, and a £126 price tag could take the top spot in this mini battle.

Signed by Bayern Munich in 2019, Jamal Musiala has already humiliated Chelsea somewhat. Less than one year after leaving the club, he was on the bench against Chelsea in the 4-1 hammering of Frank Lampard's side during the Champions League road to victory.
Since then, he has made his debut in the competition, scoring two goals in his 14 matches, and now he's started the current league campaign on fire. With four goals and an assist in three games, he is already three-quarters of his total from last season.
That has led to Bayern's great and now pundit, Lothar Matthäus, saying, "Musiala is the future of the club, and also an incredibly popular figure. Musiala makes the difference and is scoring more goals. If someone wanted to buy him now, the transfer fee would be close to €150 [£126m] million. That's not an issue anyway because he's certainly not for sale."
The talented attacking midfielder was taken off Chelsea's hands despite him being offered a new contract at the club. With a clearer sense of development in Germany, Musiala chose to get back to the country of his origin. He was born in Stuttgart and didn't move to England until he was seven, joining Chelsea soon after as an eight-year-old.
He also had a strong relationship with fellow Chelsea starlet Callum Hudson-Odoi at the time, and now the pair might both be off the books at Stamford Bridge. Hudson-Odoi has already had his own £70m offer from Bayern Munich, but the German champions were able to secure Musiala for much, much less, and now he's yet another name on a list of players that they wish they'd somehow, in his case, kept hold of.
