Recently, Liverpool announced a £39 million contract under the name Mohamed Salah. This is his second Premier League side after an unsuccessful spell at Chelsea.
Chelsea bought the Egyptian midfielder in January 2014. However, Chelsea loaned Fiorentina and then AS Roma in the second half of the 2014-2015 and 2015-16 seasons. Roma bought Salah out in the summer of 2016. Here, Salah truly shined with 15 goals and 11 assists in the 2016-17 season.
This is in complete contrast to the midfielder's 19 appearances and 2 goals for The Blues. Moreover, what Salah has put in has convinced Liverpool that he is worth £39 million.
Speaking of stars who failed while playing at Chelsea, the name Kevin De Bruyne cannot be ignored. The Belgian midfielder arrived at Chelsea at the end of the 2012 winter transfer window. However, he only played a total of 9 matches for the home team at Stamford Bridge with the time playing for Werder Bremen on an interim loan.
De Bruyne officially left Chelsea in January 2014 and by August 2015, Man City had to spend £54 million to own this midfielder. In the past 2 seasons at Man City, De Bruyne has proven himself to be a top assist player in the Premier League.
De Bruyne's compatriot - Romelu Lukaku is also a player of this type. The striker signed for Chelsea in August 2011, when the Blues were still led by coach Andre Villas-Boas. Lukaku was a member of Chelsea's squad until 2014, but in 2012 2013 and 2013, he played for West Brom and Everton on loan.
Lukaku has not scored any goals for Chelsea after 15 matches but has always been a key striker in the above two teams, especially when he officially signed for The Toffees in 2014. The 2016 2017 season was Lukaku's most impressive season, scoring 25 goals in the Premier League.
Speaking of the unlucky strikers at Chelsea, Daniel Sturridge and Radamel Falcao should also be mentioned. In the 2015-2016 season on loan to Chelsea, Falcao scored just 1 goal in 12 appearances. However, when he returned to his home team Monaco, he scored 28 goals in the 2016-2017 season.
Compared to the above names, Sturridge's achievements at Chelsea are more significant: 96 appearances and 24 goals. However, at Liverpool, the striker's scoring ability is even better: 47 goals in 84 matches. He collaborated well with Raheem Sterling and Luis Suarez in the 2013-14 season, a season in which Liverpool were a bit lacking, winning the Premier League.
In addition to the players mentioned above, some players who have succeeded after leaving Chelsea include: Oriol Romeu, Ryan Bertrand (Southampton), Juan Cuadrado (Juventus), Filipe Luis (Atletico Madrid), Thorgan Hazard (Borussia Monchengladbach). In addition, Nemanja Matic and David Luiz, although having parted ways with Stamford Bridge, have returned and reaped glory.
