12) Kevin De Bruyne
Perhaps the biggest disappointment of Chelsea fans in recent seasons has been the rise of De Bruyne. The impressive Belgian returned to Chelsea after a fine season with Bremen in the Bundesliga. De Bruyne started three of the opening five games during Mourinho’s return to Chelsea; however, soon vanished from the first team. A couple of appearances in the League Cup followed before De Bruyne left for Wolfsburg. Since his move away from Chelsea, De Bruyne has evolved into one of the best-attacking midfielders. He joined Manchester City in a 55 million Euros at the beginning of the 2015-16 season.
11) Romelu Lukaku
Another Belgian let go off by Mourinho, Lukaku finished as the top scorer in the Premier League last season. Lukaku was touted as the perfect heir to Didier Drogba at Stamford Bridge. However, he played just 122 minutes under Jose Mourinho before being sold to Everton for 28 million. Chelsea came back to sign Lukaku this summer but were beaten off by Mourinho’s Manchester United, who signed the striker for 75 million Euros.
10) Nuri Sahin
Coming from the back of an impressive season with Borussia Dortmund as the Black and Yellows won the league title in 2010-11, Nuri Sahin joined Real Madrid in what was supposed to be the next step in his career. However, the move did not work out as the Turkish midfielder regularly struggled with injuries and game time. He was loaned to Liverpool, where he struggled in an unfamiliar role under Brendan Rogers. He finally returned to Borussia Dortmund.
9) Mohammed Salah
The Egyptian was brought from Basel in January to strengthen the Blues’ attacking force in 2014-15 season. Salah enjoyed a slow start to life in England as he showed signs of brilliance. However, he failed to impress the Portuguese tactician, who only used him sparingly. Salah was loaned to Fiorentina at the beginning of the 2015-16 season. To his credit, Salah returned to his best form in Italy with Fiorentina and then Roma, which saw earn a 40 million move to Liverpool this summer.
8) Anthony Martial
Martial was the lone shining spot during Van Gaal’s tumultuous final year at Manchester United. He answered his critics, scoring in his first appearance for the Red Devils against Liverpool. Martial went on to become Manchester United’s most important player that season. Naturally, the expectations were higher from the Frenchman to build on a fine campaign. However, Martial failed to impress Jose Mourinho and often found him on the periphery last season. Martial has been linked with a possible move to Roma this summer. If the move does happen, it would be a sad ending to the Frenchman’s career at United.
7) Felipe Luis
Felipe Luis joined Diego Costa and Thibaut Courtois in leaving Atletico Madrid for Chelsea after an unexpected La Liga title win the season before. One of the best performing left-backs at the time, Luis failed to establish himself as Mourinho preferred Azpilicueta in that position. In fairness, Luiz struggled to adapt with the physicality of the Premier League. Regardless, he left the Premier League after just one season, though as a champion.
6) Ezequiel Garay
One of the most sought after defenders, Garay is usually on the list for top clubs looking for a tall, strong defender. Nevertheless, Mourinho did not rate him at all. The Argentine failed to impress the Portuguese manager, often finding himself on the bench. He left the club for Benfica, where he enjoyed great success. After three successful years in Portugal, Garay joined Zenit before finally ending up at Valencia at the beginning of the last season.
5) Ricardo Quaresma
Ricardo Quaresma was one of the few additions Mourinho decided to make when he took reins of Inter Milan. Despite his struggles at Barca, Quaresma had performed brilliantly in his homeland for Porto. He failed to make the same difference during his time in Italy however, as he was nowhere to be seen when the club won the treble. Quaresma has failed to perform consistently; nevertheless, the attacker was a prominent figure in Portugal’s Euro Cup success.
4) Juan Cuadrado
Brought in to replace Andre Schurrle at Chelsea, Cuadrado attracted great enthusiasm amongst the fans due to his tenacious style of play. The winger, however, was limited to just 15 appearances under Mourinho, most of which came from the bench. He was let go by the Blues shortly as he joined Juventus on a two-year loan. He has since won two Serie A titles with the Bianconeri.
3) David Luiz
The Brazilian was never going to be in Jose Mourinho’s plan. His playing style was in every sense totally opposite of Mourinho’s philosophy, who likes his defenders focussed all the time. As a result, Mourinho deployed Luiz in the defensive midfield, preferring a pairing of Cahill and Terry at the back. He joined PSG in a record 50 million Euros deal. However, Luiz returned to Chelsea last summer and blossomed in a three-man defence as Chelsea won the league title.
2) Andre Schurrle
The young jovial Andre Schurrle quickly smote Chelsea fans, when the German joined the club from Bayer Leverkusen. His tireless running and unselfish style of play attracted many fans but not Jose Mourinho. Despite showing signs of brilliance, Schurrle failed to establish himself as a regular in Mourinho’s lineup. After an ambivalent one and a half season at the Bridge, Schurrle left the club for Wolfsburg. He has since joined Dortmund becoming their most expensive signing at the beginning of the last season.
1) Luke Shaw
Luke Shaw has struggled to develop at Old Trafford since joining the club as a teenager from Southampton. A huge part of is down to his struggles with injuries. Moreover, Mourinho constantly reprimanding the defender has only made matters worse. He fell down the pecking order last season after Mourinho claimed Shaw was too soft. The Englishman would be hoping to fight back this season as he looks to book a place in the England team for the World Cup.
