Valencia have conceded late to relegation-threatened Valladolid in a 1-1 draw in the Spanish soccer league, adding pressure on embattled coach Marcelino.
Valencia played well but wasted plenty of chances on Saturday at Mestalla Stadium, including a penalty kick.
"These things are difficult to explain," Marcelino said. "It's not the first time we have a game like this, when we are completely superior but our opponent ends up scoring with a great goal."
An 82nd minute free kick by Ruben Alcaraz cost Valencia the home victory after Dani Parejo scored 10 minutes earlier.
Striker Rodrigo's 54th-minute penalty was saved by Valladolid goalkeeper Jordi Masip, who also stopped Santi Mina's close-range attempt off the rebound. Santi Mina, in his 100th Valencia league game, also missed an open-goal chance.
South Korean midfielder Lee Kang-in came on late, becoming the youngest foreigner to play in the league for Valencia at age 17.
It is the seventh draw in 10 home league games for Valencia, and 11th overall in 19. With only four wins, Valencia sit 10th in the 20-team standings.
Valladolid's winless streak extends to five matches in all competitions. They sit 14th.
Valencia were coming off a Copa del Rey first-leg loss to second-division Sporting Gijon, a result that prompted increased calls for Marcelino's firing.
"My job is to find solutions. If the club thinks a change in coach will help the team start winning again, and that I'm the only one to blame, then it will make the decision it needs to make," Marcelino said.
"I would accept it, but I would not agree with it ...there are things that are out of the coach's hands."
Villarreal lost to Getafe 2-1 at home, dropping them to second last. Getafe move up to sixth.
Cristhian Stuani scored with a neat overhead kick to put Girona ahead in the first half, but visiting Alaves salvaged a draw with a 50th-minute equaliser by Borja Baston.
It was the fourth-straight draw for eighth-placed Girona.
Surprise packets Alaves missed a chance to overcome Sevilla for third place. They might drop to fifth if Real Madrid win on Sunday at Real Betis.
Leganes moved further from the relegation zone, beating last-placed Huesca at home 1-0. The first win in six matches lifts them three points clear of danger.
