The Spain international impressed in the Blues' comfortable 3-1 win over Derby in the League Cup quarter-finals and believes that near-unprecedented glory is on the cards.
Chelsea midfielder Cesc Fabregas believes that they can do the quadruple this season.
Goals from Eden Hazard, Filipe Luis and Andre Schurrle gave the Blues a comfortable 3-1 win over Derby County, sending them into the League Cup semi-finals.
The Blues are also top of the Premier League and have qualified for the Champions League knockout stages, where they will face Paris Saint-Germain, while they will meet Watford in the FA Cup third round, and the Spaniard feels that the team are capable of seriously attempting a clean sweep of trophies in 2014-15.
"I'm enjoying playing in this team; we have a very strong squad and we want to go for everything," he toldSky Sports after their victory over Derby.
"We can get better, 100 per cent, and we know that. Everyone is really focused and professional but the next two or three weeks are very important.
"Time will tell [how good this season can be]. We definitely have the talent, the discipline and the courage to [win all four trophies], I'm sure of that from what I've seen so far in my short time here.
"I can see the team doing well but we will have to work hard and, at the end of the season, we will talk about it."
