Head Coach Danny Wilson admitted poor execution in the second half had ultimately cost his Cardiff Blues as they were edged out 14-13 by Leinster Rugby in a wet Guinness PRO12 clash at BT Sport Cardiff Arms Park.
In horrendous high winds and driving rain, a tight encounter exploded into life with a breakaway try from Leinster wing Isa Nacewa in the second period.
Cardiff Blues hit back with a try from Josh Navidi three minutes from time, but despite a grandstand finish from the home side they could not find another late score.
And, after playing with the strong wind to their backs in the second period, Wilson admitted a failure to execute the game plan second half had been costly.
“It’s another really frustrating result for us,” said Wilson. “There was loads of endeavour and we’ve put ourselves in great position after a first half tactical performance into the wind that was spot on.
“We kept the ball for long phases into the wind, had good shape and we defended well. We teed up the second half down-wind for us but then didn’t deliver.
“Our execution was poor second half, we kicked ball away from good position, which we didn’t need to, and we became over narrow and lost our shape, with no options and too many pick and goes.
“We made it easy to defend and it’s another opportunity where we will be kicking ourselves in the morning. Like last week, we have missed out on a great opportunity and it’s cost us results.
Meanwhile, Wilson revealed the region would monitor the fitness of centre Cory Allen over the next 24 hours after he was stretchered off with an ankle injury.
“Cory is in a protective boot at the moment and will be assessed in the next 24 hours,” he said.
“He hasn’t had the best luck so hopefully we will have some positive news and a good outcome after the assessment.
“When he has been on the pitch for us he has done well, so we hope for the best for him, for Wales and for Cardiff Blues and that’s it’s only a few weeks.”
