Cardiff Blues flanker Sam Warburton believes that his side's upcoming Heineken Cup matches against Edinburgh will be "two hard games".
The Blues have made an unbeaten start to the competition, having recorded wins over Racing Metro and London Irish.
However, Wales captain Warburton has claimed that Edinburgh will provide a sterner test.
"Edinburgh in the Heineken Cup will be two hard games for us," he told Sky Sports News.
"Winning away at Racing Metro was a huge result for us, while the win at home against London Irish wasn't pretty but it is the victory that counts.
"We are now two from two but so are Edinburgh. It should be two really close, tough games. I am just glad we are at home first."
Cardiff have never won the Heineken Cup.
