Perth Glory remain in third position in the A-League table after being held by Adelaide United.

Adelaide took the lead after 54 minutes through Osama Malik, but Chris Harold's equaliser ensured that Perth earned a share of the spoils.

The home outfit started the stronger of the two sides, but Adelaide were unlucky not to lead at half time after dominating the final 15 minutes.

However, Malik opened the scoring for the visitors nine minutes after the break after he rose highest to head the ball into the bottom corner.

Perth introduced William Gallas into the action shortly after the hour for his A-League debut, and eight minutes later, Glory equalised when Harold headed home a corner.

Both teams pushed for a winner as the final whistle approached at the nib Stadium, but neither outfit could nick the three points.
