While the move isn't official yet, the Blues are set to bring the RB Leipzig forward to Stamford Bridge.
Speaking at a press conference on Friday, Flick said: "This is a decision Timo made. And you have to respect that, everything is okay,' Flick told reporters on Friday.
"Timo is a very good player, also a player who scores.
"Chelsea made a very good commitment if that's the case."
