Spain captain Sergio Ramos insists his team have plenty to improve on after they limped into the knockout rounds of the 2018 World Cup in Russia.
The European giants have endured a tough few weeks after the Spanish Federation sacked former coach Julen Lopetegui following his decision to take the vacant Real Madrid post.
Spain were held to a 3-3 draw in their opening game against Portugal, with Cristiano Ronaldo grabbing a hat-trick.
Fernando Hierro’s men then sneaked past Iran before drawing 2-2 with Morocco on Monday night.
Spain will now take on hosts Russia in the last 16 but the 2010 world champions have yet to show their best form.
Ramos admits the mood in the camp needs to change and improve and the Madrid man has urged for more from his team-mates.
“We must change the current mood as soon as possible,” Marca quotes Ramos as saying.
“It was important to progress from the group so not everything is as bad as some people might say but the performance was not what it should be.
“We have a lot of attacking threat but in defence we must be more careful as that has cost us so far, we must reduce the margin of error because from now on, if we perform poorly we are out.”
Spain will take on Russia on July 1 and they are 1.62 to get the win. The draw is 3.80, while Russia are 6.00 outsiders.
