With Thibaut Courtois leaving for Real Madrid, Chelsea parted with a world record fee to bring the Basque shot-stopper to Stamford Bridge, paying his release clause of £71m.
However, the 23-year-old won't let that get to him and is keen to adapt to Premier League football as quickly as possible.
"I don't think there will be additional pressure for me," the Spain international said.
"The only pressure I experience is the pressure I put on myself. I am a player who demands a lot from myself and this has always been the same.
"I will try to do it the best I can and to give everything I can to the team."
