Ernesto Valverde claimed Barcelona's hectic schedule had caught up with them as the unbeaten La Liga leaders were held to a goalless draw by Getafe on Sunday. It was Barcelona's 12th game in 39 days and Valverde admitted tiredness might have been a factor. "We were lacking freshness and rhythm," Valverde said. "We can't win every game we play or be 100 per cent all the time." Barca are seven points ahead of Atletico Madrid.
