Chelsea defender Branislav Ivanovic has welcomed the arrival of Cesar Azpilicueta.
Ivanovic is relishing the competition provided by the former Marseille fullback.
"It's great to have competition between the players, it's very positive," the Serb said.
"Cesar is good, he is working very hard and he is waiting for the chance and he will show his qualities and how good he is.
"One player cannot play in one position all season long."
