One of only three teams to have won five titles in the Premier League era, the Blues are the current Champions League holders.The Blues have made their mark in the last two decades, especially since their takeover by billionaire Roman Abramovich in the early 2000s. The infusion of cash has seen many top players arrive at Stamford Bridge, helping raise the stature and pedigree of the club.In recent years, Chelsea have not hesitated to splurge, bringing in the likes of Kai Havertz, Timo Werner and Romelu Lukaku by spending the big bucks.

He has scored in four different competitions, but has netted just five times in 19 games.
