And he insists those new to the Premier League just need time to adjust.
Ivanovic told chelseafc.com: "From the beginning of the qualification for the World Cup we started to play very well, and all the guys deserve to come and play in the big clubs in England.
"Nemanja Vidic also needed time, but now he is here for five years and playing very well as Manchester United captain. We have to show our quality like a team, every single player, for Serbian football.
"I think it is great to have six or seven players in the Premier League, the best league in the world. It is great, and we all chat and speak a lot. For the new guys it is a surprise how things work here and how everything is going. Everyone has to adapt but I think they will be fine."
