Valencia surrendered the lead on three occasions on Monday evening as they settled for a 3-3 draw in their trip to Osasuna after Carlos Clerc netted an injury-time equaliser for the hosts.
Barcelona loanee Munir El Haddadi opened the scoring after two minutes when he ran on to the end of a Guilherme Siqueira cross, but Granada forward Oriol Riera equalised just five minutes later.
The tables were then turned on Riera after he headed the ball into his own net on the stroke of half-time, but Roberto Torres came to his team-mates rescue with a second-half leveller.
