Span's right back Dani Carvajal said that his team will have to be focused during their upcoming encounter against host Russia, as its players «attack very quickly,» speaking during a presser in Krasnodar on Thursday. According to Carvajal, Sunday's game will be «very, very difficult,» as Russia is the host and «they have all the country behind.» «We have to be very concentrated, motivated... Еще, and see how we exploit their weaknesses, and we should get stronger with our own weaknesses too,» he stated. Carvajal added: «We need to be concentrated in the attacks and in the defence, because these details can make you move to the next phase. Russia is a strong team, a fast team, and we need to be careful when we lose the ball, because they attack very quickly. They are really good at the transition defence-attack, so we need to be concentrated there, because they can harm us.» The defender estimated that the level of performance should increase in the round of 16, as «matches are life or death». He also said that taking for granted that the strongest teams have to win the weaker ones is a «mistake,» as happened with South Korea's 2-0 win over Germany, and its disqualification. Spain will play against hosts Russia on July 1.
