The Catalans travel to San Mames knowing a victory could seal the title should Real Madrid suffer defeat in the derby against Atletico Madrid later in the evening, and Song is hopeful he will soon be able to get his hands on his first league title since leaving Arsenal last summer.
"It will not be easy," he told reporters. "Athletic Bilbao are a great side, especially at home, but since my arrival here my aim has been to win titles.
"We have to respect Athletic, it will not be a simple game. In addition, we have to hope for a favourable result in Madrid. Better, however, that we just think about our game and winning. Later, we will see what happens."
Song has failed to estabish himself in Tito Vilanova's first-team plans since moving to Camp Nou for €18 million last August, but he insists he is not discouraged by his relative lack of playing time.
"I still have confidence and I am working hard in order to be able to play in midfield and defence," he concluded.
