Gianfranco Zola has wished incoming Chelsea manager Frank Lampard best of luck, despite him leaving his assistant manager role at the club.
Zola worked under Maurizio Sarri last season but has been relieved of his duties with the Italian manager having left the club for Juventus.
Lampard was officially unveiled on Thursday as the club's new manager, which coincided with Zola's departure.
"I am very happy for Frank. It is a great opportunity for him and I really hope he does well," said the Italian, who spoke to The Sun.
"I hope he is going to be a total success. It will not be a walk in the park. It is a big challenge but big challenges make big coaches," he added.
He thanked the club and fans for the chance to work at the Bridge, further saying the opportunity benefited him immensely.
"It was important that it helped my career. Working for a top club with a top coach has been good for me," he explained.
"I was head coach before and my main ambition is to return to that. But to work for Maurizio and Chelsea was a great opportunity. What matters is it was a great year and I have been part of a winning team, Chelsea is in my heart and I was so proud to achieve so much for the club," he added.
Lampard will take charge of the team in their first preseason session in the next few days, with some of the stars missing.
