Zabaleta has only just joined up with the squad after he was granted an extended break after his wedding. The Argentina defender revealed he has been impressed with the changes while he was away.
Zabaleta told the Manchester Evening News: "I think (Pellegrini) is a great coach and a great person. When I met him he made a great impression.
"Big players are always very welcome at this club. I know Negredo and Navas more than Jovetic because I have been three years in Spain, I played three years in La Liga and played against them. They are very good players.
"Jovetic is a very interesting player, he did very well at Fiorentina and if the club and Manuel Pellegrini signs them it is because the manager knows they are good players."
