Chelsea loan man Tomas Kalas believes he can get to the standard required to be a Chelsea first team regular at Fulham.
The Czech star signed a new four-year deal with the Premier League champions, then immediately renewed his season-long loan move to Craven Cottage.
The centre-back told ctsport.cz that he had only spoken "five or six words" to Blues boss Antonio Conte, but believes he can use his second spell with Fulham to prove he has what it takes to be a Premier League players.
He said: "I have to prove somewhere that I have Chelsea level. That I played two matches under Mourinho does not mean I have a Premier League [quality]. I have to get to that level and it certainly will not help me to be anywhere else every year.
"That is why I try to return to the same club where I would like to last for two, three years. It only moves me on and maybe it will help me once in Chelsea."
And Kalas says the minimum goal for the Whites this season is the Championship play-offs.
He added: "We want to play at least for the Premier League play-offs. A lot of teams have strengthened so the competition will be cracked by big names.
"But we have high ambition. Last year they were not, because no one expected it. In the end, it swung around and we all wanted to get there. Now it is expected and we will play under a little more pressure."
