The Gunners once again shot themselves in the foot with some basic mistakes in their 19-18 defeat against a Leinster team shorn of stars such as Brian O’Driscoll who are preparing for Ireland’s international against South Africa.

That has been a familiar story for Edinburgh, whose last five defeats in all competitions have been by eight points or less, leaving Paterson frustrated.

“It is a huge opportunity missed,” said Paterson who finished with 13 points.

"So many individual errors basically strangled our own game. Credit to Leinster, no matter who they field they are a hard side to play against especially when they are cheered on by a big crowd.

“It is a tough ask but it was definitely one, if we had cut out the mistakes, we could have come away with a victory."
