Liverpool goalkeeper Alisson Becker insists it is too early to assess his start to his career in England after admitting he was expected to be perfect after his £65million transfer.
The 26-year-old briefly became the world's most expensive goalkeeper with his move from Roma in the summer and his start to the campaign appears to have justified the Reds' significant outlay.
He has kept seven clean sheets in 12 Premier League appearances and just five goals conceded is the club's best return in the competition after a dozen matches.
Alisson had one major hiccup when he conceded a goal at Leicester trying to trick his way out of trouble and the Brazil international believes it is premature to deliver a verdict on how he is performing.
He prefers to share the credit with the likes of Virgil van Dijk and Joe Gomez, who have done so well in the back four in front of him.
"I came here for a high price and some people expect to me to be perfect - it is not easy but I'm trying," he told reporters ahead of Brazil's friendly against Uruguay at the Emirates Stadium.
"It is really early to say if I'm satisfied with how I'm playing but I'm working to be perfect, I'm working to be better.
"I am really happy with my move to the Premier League. I'm working really hard to help Liverpool to achieve their goals.
"One thing that is important here is the concentration and focus. They are asking me to be really mentally strong.
"My team have a really great defence so it is not often the ball comes near my net but I have one or two opportunities to show my quality, so I need to be focused all the time."

Gareth Bale, Sergio Aguero and Alisson Becker are among the first nominees announced for this year's Ballon d'Or award.
The honour, now separate from FIFA's own Best player of the year award, is bestowed annually by France Football magazine with the 30 nominees announced in groups of five, in alphabetical order.
Wales star Bale - whose bicycle kick against Liverpool helped clinch the Champions League for Real Madrid - joined Manchester City striker Aguero and Liverpool keeper Alisson in the first batch.
Bale's club-mate Karim Benzema and Paris St Germain striker Edinson Cavani were the other names in the initial quintet.
Liverpool manager Jurgen Klopp has every faith new goalkeeper Alisson Becker will settle quickly into the Premier League.
The Brazil international was, until Chelsea signed Kepa Arrizabalaga this week, the world's most expensive goalkeeper following his £65million move from Roma.
His recruitment is seen as a key piece of business for Liverpool, strengthening an area which has been open to criticism for several years.
Alisson came to pre-season training later than the main group because of his involvement in the World Cup and has played just two friendlies against Napoli and Torino in the last six days.
However, Klopp has no worries about the 25-year-old making an instant impact.
"Just be a goalkeeper. Be yourself, in this case, because he is very calm and laid back - and that helps," said the Reds boss ahead of Sunday's visit of West Ham.
"It's about making the right decisions in the right moments. It's all good. He's settled really quick, as if he's been here longer than two weeks. That's all fine."

Roma's sporting director Monchi has stressed selling Alisson "would not show a lack of ambition" as he confirmed the player was in Liverpool on Thursday.
Press Association Sport understands Liverpool have agreed to meet Roma's valuation of 75 million euros (approximately £67m) for Alisson, a figure which would make the 25-year-old Brazil international the most expensive goalkeeper in history.
On Wednesday, Italian website Forza Roma, which is affiliated to newspaper La Gazzetta Dello Sport, published a video which it said showed Alisson at Rome's Ciampino airport. It said he was preparing to board a private jet to Manchester and was on his way to Liverpool for a medical.
Speaking on Thursday at a press conference to present Roma's summer signing Justin Kluivert, Monchi was quoted on the Serie A club's official twitter feed as saying: "We haven't finalised anything yet (with Alisson).
"But it is true that the negotiations are advanced and he's over in Liverpool now."
Monchi, who took up his post at Roma in 2017, added: "When a very substantial offer comes in, you have to consider it.
"We weighed up the pros and cons and decided to speak to Liverpool.
"Selling Alisson would not show a lack of ambition. For me, ambition is about doing the right thing after thinking everything through.
"I came here to build a strong team, not just for one year but for many years to come - and I'm 100% sure that will be the case.
"I understand the fans' view. I want them to know we're working to build a stronger team.
"Some people never thought we'd be able to sign Kluivert. The same goes for (fellow summer signing Javier) Pastore.
"Perhaps today is tough for some fans, but we've brought in top players."

Liverpool are closing in on a world-record deal for Roma goalkeeper Alisson.
Press Association Sport understands the Reds have agreed to meet Roma's valuation of 75 millions euros (approximately £67million) for the first-choice Brazil international.
The current record transfer in pounds for a goalkeeper is the £35million paid to Benfica by Manchester City for Alisson's compatriot Ederson last summer, while the highest price in euros was Gianluigi Buffon's 53 million move to Juventus back in 2001.
Liverpool boss Jurgen Klopp has given public backing to Loris Karius following his calamitous Champions League final performance but has made signing a goalkeeper a priority.
The club are not prepared to say anything publicly until the deal is completed and as yet no medical has been arranged, with the possibility remaining that another club could match Liverpool's offer.
Chelsea have also been linked with the 25-year-old, who began his career with Internacional before moving to Roma two years ago.
