Athletic Bilbao's Champions League Group H clash with Shakhtar Donetsk at the San Mames remains goalless at half time.

The home side's second appearance in the UEFA Champions League group stage, and their first since 1998-99, began slowly, with few chances of note in the opening stages.

Ibai Gomez and Oscar de Marcos enjoyed occasional forays down the touchline, but the final ball has been lacking for Athletic Bilbao.

Gomez whipped a free kick into the side-netting after 28 minutes, but that was as close as either side came to a breakthrough.

Shakhtar Donetsk had Darijo Srna booked after 30 minutes for time-wasting, with Taison also going into the book for simulation five minutes later.

Iker Muniain briefly raised pulses when he burst into the box five minutes before half time, but he could only find Shakhtar Donetsk goalkeeper Andriy Pyatov with his cut-back.

Aritz Aduriz had a case for a penalty when he tumbled in the box under the challenge of Yaroslav Rakitskiy just before half time, but referee Anastasios Sidiropoulos was unconvinced.
