Valencia are one of the best teams in the Spanish League due to their experienced and quality players, Barcelona coach Frank Rijkaard said ahead of their game in the Nou Camp on Sunday. "They are a much disciplined team," the Dutch coach was quoted as saying by sports daily El Mundo Deportivo. "They retreat back fast in defense and they have players who can make all the difference in attack." Defending champions Barcelona failed to beat Valencia last season as they were held to a 2-2 draw at home before losing 1-0 away. Valencia had a great start this season, winning their first three games and splitting the summit on nine points with Sevilla and Barcelona themselves. They also issued a European warning note with their 4-2 away victory over Olympiakos in their Champions League group opener. Rijkaard refused to name certain sources of danger within the visitors' squad and warned against falling back to them during the game. "They have many intelligent and experienced players who make the team one of the best in the league," Rijkaard added. "And if they have the lead, Valencia are capable of making life much more complicated."
