Chelsea boss Thomas Tuchel says he will always have a "close bond" with Pierre-Emerick Aubameyang after working with the forward at Borussia Dortmund.
Aubameyang moved to Barca in February after a disciplinary breach at Arsenal and Tuchel said he was still close to the player after their time in Germany.
"I experienced no issues with him," said Tuchel on Friday.
Tuchel refused to discuss the prospect of signing Aubameyang this summer but was happy to discuss his experience of working with the player at Dortmund, where the Gabon forward spent five years before joining Arsenal in 2018.
