Try-scoring centre Cory Allen insists Cardiff Blues are on the right track and once individual errors are cut out the wins will start to come.
Welsh international midfielder Allen helped spark a second half fight-back as he grabbed the first of two tries in three minutes from Cardiff Blues as they raced back to 27-23.
But a try from Leinster with the last play of the game left Blues empty-handed and Allen to reflect on defeat at the RDS.
He said: “We lost the game so we are obviously not happy, but when you look at the way we have played, it is little individual errors that have cost us. Leinster are one of the best teams in Europe and if you give them a sniff the take it.
“We are disappointed to have lost the third game on the bounce. But in each of those games we have been close and are playing some good stuff. We lack that clinical edge at the moment and when we give the opposition a chance they are taking it.”
“We felt we were going to get the draw,” he added. “When you are out there on the field you get feel of the momentum and it felt like it was with us. But they turned us over in injury time and were straight under the posts.
“It is frustrating because we have lost, but we have a new coach in Mark Hammett and he is bringing some really good things in. It’s a learning curve with what he has brought over; it was always going to be that way. The feeling is one win will get the ball rolling.”
Next up for Blues is another trip to Ireland on Friday night to face Connacht (kick-off 7.35pm) before a Welsh derby a week later with another away day at the Liberty Stadium and the Ospreys.
“It doesn’t get any easier and Connacht are playing good rugby,” said Allen. “Up in Galway is tough and then the Ospreys and a big rivalry. But first we focus on next week and cutting out the individual errors.
“We know that expectation that comes with playing for Cardiff Blues. With the players we have and have recruited, we are stronger. Expectations are high, but this is a new group under a new coach and that takes time. But we have the foundations right.”
