He knows the Premier League and, after three years together here, he knows everything and that's so important.
"We have a limit and cannot spend more so that's why we need to be careful with the players and try next season to see what we can do to improve".
Guardiola acknowledges he can not expect Fernandinho, signed from Shakhtar Donetsk in 2013, to play as much for City as he gets older, adding a solution has to be found for next season.

"Gündogan played the last two games like a holding midfielder [against Rotherham United and Burton Albion], he had more space than usual - but he was so clever".

Of course, in all departments in the club, we have in every position four or five or six options - depending on age, what we believe and, of course, the price.
Guardiola would not be drawn specifically on City's interest in De Jong but admitted it is rare to beat Barcelona to a signing. "That's why they are doing incredibly well in the Premier League".
'It would be a dream, everyone is invited, ' Guardiola said.
"I am in touch quite often with Txiki, especially, because he is close to my door. I don't talk about players not here, never did and never will".
"If he has a problem he knows where I am, so I don't know, really. It's complicated, so, so complicated".
