This week saw Mohamed Salah return to the Premier League, after signing for Liverpool for around €42m.
The midfielder had previously played for Chelsea, but failed to be given a real opportunity in the Blues’ first team; however, he’s in quite illustrious company in this regard, as a number of top midfielders have been sold by the reigning Premier League champions.
Here’s a look back at six examples over the past few years…
1. Kevin De Bruyne
De Bruyne was bought by Chelsea in 2013, and after loan spells with Genk and Werder Bremen, the midfielder was deemed to be ready for first team football at the Bridge.
However, he lasted just half a season under then manager Jose Mourinho, who clearly wasn’t the Belgian’s biggest fan.
De Bruyne returned to Germany, this time with Wolfsburg, before joining Manchester City in 2015 for an estimated £55m.
2. Thorgan Hazard
Thorgan Hazard joined Chelsea just a few weeks after his brother, Eden, had moved to the club.
Hazard only ever represented the club once, in an U21 game against Manchester City. The youngster was sent on loan to Belgian side Zulte Waregem for two years, before joining Borussia Monchengladbach on a short term deal.
The Bundesliga side were so impressed with the Belgian that they signed him permanently in 2016, where he scored 11 goals in all competitions last season.
3. Marko Marin
Marin was considered to be one of Germany’s most promising midfielders by end of the ’00’s and subsequently earned a move to Chelsea.
However, the winger never established himself in the first team, and after just a year at the Bridge was deemed surplus to requirements.
Marin spent time on loan with sides such as Sevilla, Fiorentina and Anderlecht, before finally agreeing to join Olympiacos permanently in August 2016.
4. Juan Mata
In his first two years at Chelsea, the Spaniard won the FA Cup, Champions League and Europa League, as well as being voted Player of Year in both seasons.
Yet Jose Mourinho’s return to the club marked the end of Mata’s association with Chelsea, as it was deemed he lacked the necessary defensive work rate.
Mata moved to Manchester United in 2014, where ironically he is once again managed by Mourinho.
During a four-and-a-half year stint at Stamford Bridge, Oscar established himself as a regular in the side.
However, Antonio Conte struggled to find a place for the Brazilian in his 3-4-3 formation and after a huge £60m bid from Shanghai SIPG last January, Oscar departed for the rich pastures of the Chinese Super League.
6. Andre Schurrle
Like a few others on this list, Schurrle failed to hold down a regurlar place in the Chelsea side during Jose Mourinho’s second coming.
During his time in England, the German proved his worth by helping Germany win the World Cup, where Schurrle provided an extra time assist in the final.
However, at club level the likes of Eden Hazard and Willian were preferred above the German, and due to limited playing time he left Chelsea in 2015 to join Wolfsburg.
