Chelsea centre-back David Luiz has claimed that the Blues will have had a "s**t season" if they finish the campaign without silverware and refused to commit his future to Stamford Bridge.
The Blues' chances of winning a trophy are slim after their recent defeat in the Champions League semi-final against Atletico Madrid left them relying on a miraculous recovery in the Premier League to win the title.
To snatch the Premier League trophy, Mourinho's side will need to win their remaining two games against Norwich City and Cardiff City and hope Liverpool and Manchester City drop points.
And after Eden Hazard recently questioned Mourinho's style Luiz has now admitted that Chelsea's season will be declared a failure unless they win the Premier League.
"You can say it is a s**t season if you don't have trophies in a season at a big club, that is true. The season we won the Champions League [in 2012] was a s**t season until the end and then we won two titles," Luiz was quoted as saying by The Guardian.
"We are a big club and we want to win trophies, but the most important thing is to have a personality. You need to fight in many situations. This is sport, this is football. Everyone speaks about results, that's true.
"If there were many poor games, when you didn't play, didn't run, didn't give your best then fine, but we gave our best in many, many games like Wednesday, but sometimes it's possible to win, sometimes not. Now, we keep fighting in the league because mathematically we can win. We cannot win automatically, it will be difficult."
And at the same time Luiz claims that his future at Chelsea remains uncertain, with reports in Spain claiming that he will be tempted by a summer move to Barcelona.
"My future is about God. I do my job every day and this is all I can do. Next season there is a plan at Chelsea. We have many, many fantastic players and everyone wants to win trophies because it is normal when you sit at home on the sofa and watch television to see Chelsea fighting for trophies."
