Biarritz head coach left fuming at official after defeat
Biarritz head coach John Isaac was left fuming by Scottish referee Peter Allen's performance as his side suffered an opening 22-10 Heineken Cup defeat against Gloucester.
England international Olly Barkley punished the French club's indiscretions, kicking four penalties to give Gloucester a flying start in Pool 6.
But Biarritz coach John Isaac said: "I thought we deserved at least a point from the game.
"It [the refereeing] was very one-sided. There were things that were blown against us that weren't blown against them.
"Having said that, our discipline was very poor - and there are a few things we need to look at."
Isaac ruled out the possibility of any official complaint against Allen, asking: "What's the point?
"I don't think it is something we will be looking to do. It was a bit of a mystery for us coming here tonight, not knowing how the game was going to be refereed.
Debut
"I don't think there was a lot of explanation on the field tonight."
Barkley, meanwhile, kicked Gloucester to a vital victory at Kingsholm - but there was little to suggest the west country club will mount a major challenge for Cup honours this season.
Barkley landed four penalties and a conversion of James Simpson-Daniel's 39th-minute try, on his Gloucester European debut.
Gloucester boss Dean Ryan admits there is a lot of work to be done before next Sunday's Millennium Stadium appointment with Cardiff.
Biarritz, despite a Jean-Baptiste Gobelet try and Julien Peyrelongue drop-goal and conversion, had to content themselves with a nil return in terms of points.
But they will head home safe in the knowledge their qualifying Pool has a long way to run.
Ryan said: "I am really pleased with the result - it was a big step for us. It is an even bigger game for us now against Cardiff next week."
