Chelsea fans have started to become frustrated at Jose Mourinho's decision to continuously overlook Juan Mata.
The Spaniard - despite having been Chelsea's best player last season - has been used sparingly this season, due to Mourinho's preference to play Eden Hazard, Oscar and Willian or Andre Schurrle behind the main striker.
Mourinho even decided to turn to Kevin De Bruyne on Tuesday when Chelsea were in need of a goal against Basel.
The Portuguese tactician decided to leave Mata watching helplessly from the bench, which must have been a bitter pill to swallow for the 25-year-old.
Chelsea fans, pundits and probably even Mata's teammates do not understand Mourinho's decision to omit the Spanish international from his side.
Mata scored an impressive 20 goals and claimed 13 assists in the Premier League for the Blues last season.
The Chelsea star, who moved to Stamford Bridge for just under £24million in August 2011, has lost his place in Spain's squad due to the lack of game-time he is currently receiving under Mourinho.
Mata will be desperate to break back into the Spain squad ahead of next summer's World Cup in Brazil - and the only way he can do that is by playing first-team football week-in, week-out.
The former Valencia man deserves to be playing in the biggest competitions as he is one of the best footballers on the planet.
If Mata does not manage to worm his way into Mourinho's plans, then he will have no choice but to jump ship in January.
Mata would break Chelsea fans' hearts if he was to leave the west London outfit in January - but the only person they should blame for his expected departure is Mourinho.
