Athletic Bilbao's Aritz Aduriz has admitted that his current goal drought is concerning.

The Spaniard, who has not found the net since January's 1-1 draw with Real Betis, believes that his recent slump has contributed to his team's dip in form.

"It is quite a few games now without scoring and the team is suffering. I want to end this streak and hopefully I can do so from Saturday," he told reporters.

"There are many things to explain why you may not be scoring the goals.

"I can only continue to work well and I am convinced that they will come. All the players are working and in the end the goals will come. I hope it is soon."

Bilbao go into this weekend's La Liga clash with Osasuna on a run of one win in five games.
