After falling behind to a strike from Wayne Rooney midway through the first half, the Basques put themselves within touching distance of the quarter-finals with goals from Fernando Llorente, Oscar De Marcos and Iker Muniain. However, Rooney struck again from the penalty spot in the dying minutes to leave the round of 16 tie delicately balanced, as Bielsa conceded in his post-match press conference. \"There is still one game to go [the second leg] so what we have achieved today [Thursday] will only have value if we repeat it next week,\" the Argentine told reporters after the game. Despite having racked up three precious away goals, Bielsa is taking nothing for granted ahead of the return fixture. \"An indication of the type of opponent we face is that they needed very few chances to score two goals,\" the former Chile boss pointed out. The second leg at San Mames gets underway at 18.00CET next Thursday.
