Chelsea midfielder Nemanja Matic insists the Blues can win the quadruple this season.
The Premier League leaders are through to the Capital One Cup semi-finals, the last 16 of the Champions League and have an FA Cup campaign to come.
Boss Jose Mourinho has consistently said that winning all four will prove to be beyond them.
But confidence is high within the squad and holding midfielder Matic, whose role in toughening up the Chelsea spine has been key, can see the club making a serious tilt for every trophy.
“I think it’s possible. We have a chance,” he said.
Matic said: “I don’t want to say that we’re going to but we’re going to try. We have quality. We will see if we can do. But I am confident, I believe in my team, my team-mates, so everything is possible.”
The 26-year-old embarked on a second spell at Stamford Bridge in January, three years after moving to Benfica when opportunities at Chelsea were limited.
The next test comes against West Ham on Boxing Day.
Matic added: “It’s always important when you are mentally prepared to win and, in this moment, we are confident.”
