Christian Benteke played 45 minutes for Aston Villa as the Premier League side suffered a 2-0 pre-season friendly defeat to Luton at Kenilworth Road.
The Belgium international, who signed a three-year contract extension last Friday after withdrawing his transfer request, could not find the net against the non-league outfit.
The Hatters went in front before the break when Mark Cullen's cross was turned in by Jon Shaw from point-blank range.
Benteke was substituted at half-time and Paul Lambert's side came close to equalising through Callum Robinson, but he could only head wide of the target when well placed.
And with just over 10 minutes to go Jake Howells made it 2-0 to Luton as he took advantage of a slip in the Villa defence and showed good composure to slot home.
