Koeman reveals he turned down barcelona job after valverde sacking

I think there may be some confusion here!

Ronald Koeman, the former Netherlands national team manager and current manager of Barcelona, has not revealed that he turned down the Barcelona job after Ernesto Valverde's sacking.

In fact, Koeman was appointed as the new manager of Barcelona on August 19, 2020, just days after Valverde's departure. Koeman has been managing the team ever since and has been leading the team in La Liga and the Champions League.

It's possible that you may be thinking of another manager or situation. If you could provide more context or clarify what you're referring to, I'd be happy to try and help!
