Arsenal goalkeeper Petr Cech has said he joined the Gunners from Chelsea because he believed they were capable of regaining the Premier League title.
Cech, 33, won the title four times during his 11-year stay at Stamford Bridge but left in the summer to move across London.
The Cech international now boasts a career total of 170 Premier League clean sheets, beating the record set by David James, after helping his club to a 2-0 win against Bournemouth that took them to the top of the table.
He said it "was not an easy decision" to move to the Emirates Stadium but added: "I always wanted to go to a team which could win.
"If I didn't believe that I was going to a team which could win, then I don't know why I would come.
"I play football not to only enjoy it -- and I love the challenge of playing and competing with the best players -- but I want to have the chance to win games.
"I believe this team has the qualities to win games, and hopefully we will manage to go all the way in the league. I believe this team has the capabilities of doing it."
He said the Premier League was "very interesting this year because the table keeps changing every other week."
But he added: "As long as we are there in March and are in a position where we can win the league, then it's fine -- it will only depend on us."
He said the fact that he faced playing far fewer games at Chelsea after former manager Jose Mourinho selected Thibaut Courtois as his No. 1 meant he "started to make the decision to come here and to play."
And he added: "You have to be consistent in your work, consistent in your performances, because if not then you might not have as many games as you would like."
The Czech Republic international explained that his linguistic abilities - he can speak English, French, Spanish and German -- meant he could communicate with all his teammates.
He added: "Sometimes foreign players wouldn't know what you say. That's when you realise it's easier to say it in their language than hoping they will understand. It can happen."
