Glasgow followed up their opening-day victory over Leinster with a 33-12 win over Cardiff Blues on Sunday.
Speaking in the Scotsman, Chris said: "Obviously we are only two games into the season and while we are very happy to have beaten both Leinster and Cardiff, there is still a lot more to come from us.
"We felt like we did not quite click against Cardiff and there were areas we can and must improve on before we face the Dragons at Rodney Parade on Saturday.
"There was a period when our scrum creaked a bit in the second-half and Cardiff made it very hard in the breakdown for us, where it was as physical as I have experienced things for a long time.
"Our ball security was not what we would have wanted, also when you have the three tries you'd obviously like to add a fourth to collect the bonus point, but we didn't quite manage that.
"That all said, we are only two games in to the new campaign and we are very pleased to have the two victories to our name against sides of the calibre of Leinster and Cardiff.
"But we have plenty to work on this week before we return to Wales."
