Barcelona travel to Real Madrid on Saturday (12pm) for the first El Clasico of the season.
Ernesto Valverde’s side are yet to taste defeat in the league this term and are 11 points clear of their rivals at the top of the table.
And Marc-Andre ter Stegen has admitted he will be doing everything possible to ensure Barca’s unbeaten run continues, including keeping tabs on Sergio Ramos.
The Real Madrid captain has a habit of scoring decisive late goals and the Germany goalkeeper is not prepared to be undone by another at the weekend.
“A goal from Real Madrid hurts like the others,” Ter Stegen told Spanish newspaper El Pais.
“But if I have to say one that bothered me a lot, it was last year when Ramos scored in the 89th minute.
“He left me with a very bad feeling.”
However, Ter Stegen knows what Barca must do if they are to come out on top at the Bernabeu – something they have managed on their last two league visits.
“The two teams facing each other are perhaps the best in La Liga and the world,” he added.
“We already know who we will have up front, and we must be aware of their attack, and of all of them…
“But also of our way of playing, that’s how we usually have the best chance of winning.”
