Blues boss Steve Bruce handed starts to four of his five summer signings with the fifth, Julian Gray, named amongst the subs.
Osasuna included former Villa striker Savo Milosivic in their starting eleven and when his name was read out just prior to kick-off the cheers matched those of the Blues team names.
The first half saw few chances created with defender Martin Taylor coming close twice from corners and substitute Clinton Morrison firing wide when well placed just before the break.
One noticeable incident in the first forty-five minutes was the sight of record signing Emile Heskey being stretchered from the field after only 18 minutes with a twisted knee. The England centre-forward was shipped off to hospital straight away for scans.
Blues made one change at half time with Gray coming on for Damien Johnson and the former Crystal Palace winger seemed to ignite a little life into what had been a very poor game up until then.
Just past the hour mark Steve Bruce made another substitution when Stern John replaced Mikael Forssell but it was the visitors who took the lead on 75 minutes. 
Upson was forced into conceding a corner and Lopez's dead ball kick was met sweetly in the box by substitute Valdo to head home unchallenged from 12 yards out.
Blues replaced Muzzy Izzet and Robbie Savage with Stephen Clemence and Jamie Clapham on eighty minutes as they went in search of grabbing an equaliser.
John did well to get a header on target from a Morrison knock down on 82 minutes and moments later Morrison himself came close when his shot was saved by the feet of Osasuna keeper Sanzol at the foot of the post.
On 86 minutes Blues leveller finally came when Clapham's left footed deflected drive from 18 yards out decieved Sanzol and crept in at the left hand post.
All in all a very dull affair but the boiling hot weather most certainly wasn't helpful.
Blues: Maik Taylor, Melchiot, Lazaridis, Martin Taylor, Upson, Johnson (Gray, 45),Savage (Clapham), Izzet (Clemence, 80), Gronkjaer, Forssell (John 61), Heskey (Morrison, 18).
