Barcelona great Rivaldo was left unimpressed by the way the club sacked Ernesto Valverde on Monday.

Valverde was dismissed after taking the morning training session and swiftly replaced by Quique Setien.

Rivaldo told Betfair: "It is clear that Barcelona did not manage this change of coach well.

"They were a bit naive and perhaps disrespectful to Valverde. It is never a positive action to start negotiating with a new coach while the current one is still working.

"Of course, Xavi and Ronald Koeman rejecting their proposals also added to this problem, creating a lot of speculation, before finally announcing Quique Setien.

"Football is a breathtaking endeavour, of course, but we all know that the process was not well conducted by the Barca board of directors. Clubs like Barcelona or Real Madrid should always have backup coaches to avoid such situations."
