Struggling Valladolid earns rare point against 10 men

But the dynamic changed seven minutes later when Las Palmas's Scotland defender Scott McKenna was shown a straight red card for bodychecking Valladolid's Anuar Tuhami as he ran through on goal.

Valladolid pushed forward for an equaliser but it took the team with La Liga's poorest offence until the 62nd minute to get the breakthrough.

Substitute Juanmi Latasa headed a knock down into the net from close range.

Valladolid, owned by former Brazil striker Ronaldo, remained rooted to the bottom of La Liga, six points adrift of second-from-bottom Alaves.

"We'll keep believing until it is mathematically impossible," Latasa said of the team's survival hopes. "I wish people could see how we work."
