The coach of the Dutch National Team, Ronald Koeman, claimed to have been offered to handle Barcelona when Ernesto Valverde was fired on January 13, 2020 yesterday. However, at that time Koeman immediately flatly refused the offer to coach Barcelona.
The reason Koeman refused Barcelona was because he felt he still wanted to train the Dutch, because of that he didn't accept the offer to replace Valverde. According to Koeman, now is not the right time to leave the Netherlands.
Refusing Barcelona does not mean that Koeman no longer loves the club, but he cannot leave his job as a Dutch coach because he has not yet joined the Euro Cup. But if the Euro has been implemented then Koeman will definitely accept the proposal of Barcelona.
