Since Abramovich time, Chelsea has changed to be one of most successful clubs not only in England but also in Europe. I don't know the stats about total trophies they have won in 21st century, but I knew Chelsea have won 2 Champions League, 1 Europa League and 1 Conference League titles in Europe. It is impressive and they are the only club so far have ever won all these three trophies.
They are returning to winning mode with recoveries in two latest seasons and the trophy in FIFA Club World Cup with an impressive win against PSG in the final match. Cole Palmer, who is in the graphic, is a core player in this generation that possibly helps Chelsea winning some more trophies in coming years.
indeed since the abramovich era, chelsea has undergone significant changes. they have gone from a middling club to a european giant. abramovich's approach of massive investment by recruiting top players and managers makes chelsea stronger. with his backing, chelsea didn't just become competitive, they became serial winners. over nearly two decades, the club lifted 21 major trophies, it has successfully transformed chelsea into one of the best clubs in europe. although abramovich is no longer chelsea's owner, he leaves behind a remarkable legacy in the form of a strong club foundation, a winning mentality, and an undeniable reputation.
