Valencia legend Miguel Angel Angulo says Ronald Koeman was not good enough to manage the club.
The Spaniard was one of the club's storied players, having joined in 1996 and won two La Liga titles and the UEFA Cup.
It was an unpopular decision at the time, and despite winning the Copa Del Rey final, the Dutchman was sacked in late April 2008.
Asked by Tribalfootball who was the best manager he worked under at the Mestalla, Angulo replied: "I've played under some great managers. There were 2 periods with [Claudio] Ranieri and the first era was spectacular.
"On the other hand, my experience with Koeman was not a good one. I don't believe that he was good enough to manage the club. He had a lot of problems with the players and created a bad atmosphere within the team. I don't believe that Koeman was prepared to manage Valencia CF and he started to make decisions that were very prejudicial for the team, including separating the team into 2 groups for training. Banishing players (Angulo, Cañizares, Albelda) did a lot of damage to the team.
"Under Quique Sanchez Flores, we were really good as a team and it was a great year but I believe the club's decision to sack Flores was too hasty as we were in a very good position in La Liga at the time."
