The former Italy and Fiorentina boss is set to take charge after Pako Ayestaran's sacking.
“He is a Coach of great experience who did well with Fiorentina and the Italy team," Capello told Cadena Ser.
“He knows football well and loves to speak with the players. It could well be an excellent decision by Valencia.
“His style of football depends on the players at his disposal. At Fiorentina he had a very attack-minded and spectacular approach, because he had the players that allowed him to do it."
