Sean Lineen admits Glasgow must improve their ability to dominate possession if they are to trouble the top teams in Europe.
The Warriors suffered a bonus-point defeat at the hands of Bath in the return fixture of their Heineken Cup double bill.
The defeat left Lineen’s men with just four points in what is admittedly a tough group – but the Scotland assistant coach wants more from his side.
They now turn their attentions back to league action with the 1872 Cup match against Edinburgh at Murrayfield on Boxing Day.
The Glasgow coach and former Scotland centre said: “We made it easy for Bath. It was very disappointing. You can’t give a team like Bath that much ball. If the platform’s not there, you’re going to struggle.
”The guys were buzzing when we were 13-8 up at half-time. I can’t fault the players for their effort and they were bitterly disappointed too.”
