Arteta believes the fact Guardiola signed a new deal at Man City shows he is really happy there.
Arsenal manager Mikel Arteta said in his press conference on Friday that he is 'very pleased' for his former boss Pep Guardiola, who signed a new contract at Manchester City.
Guardiola put pen to paper on a new two-year deal at the Etihad on Thursday.
The ex-Barcelona and Bayern Munich manager's current deal with the Cityzens now runs up until the summer of 2023, meaning he will stay with the Manchester club for seven years following his arrival in 2016.
"I’m very pleased for him," said Arteta, who joined Guardiola as an assistant coach at City in 2016, before joining the Gunners last season.
"He’s never been so long at a football club. The fact he is extending his contract means he is extremely happy there.
"He is finding his players, he feels valued, he has the chemistry that I know with the players, the fans, and the owners.
"Knowing him and his ambitions and how competitive he is, unfinished business means he wants to win every competition, every year for sure. If he needs to win the four domestic trophies again and he can do it he will try to do it.
"Obviously Europe is a massive thing. He really wants to move the club towards that Champions League win and that’s in his way. I think medium to long term that was one of the things he wanted to achieve."
When asked about a report of a training-ground grapple between Brazil defender David Luiz and Spanish midfielder Dani Ceballos, Arteta said: "Nothing. Training is very competitive and issues happen a lot of times and those things get resolved immediately within the team and not much to say. No problems at all.
Asked if he saw what went on, he answered: “I have a really bad vision from afar. That’s why we train behind closed doors.”
