Wales had only a Non Evans’ penalty to show for their efforts as they were comprehensively outplayed by Ireland in their third defeat of the Championship.

And Lewis believes basic errors have proved costly throughout the course of their campaign.

He said: “We aren’t doing the simple things well at the moment. We are not quite firing on all cylinders like we did last season.

“The bottom line is we weren’t good enough. We lost the contact area and lacked composure and we have to take a long look at ourselves.

“We were in control for the first 25 minutes of the first half but we then gave away a soft try before giving away a series of penalties late in the first half.

“ We gave field possession away which handed momentum to them.

“In the second half Ireland came out and played a kicking game and pinned us back and we couldn’t get out of our own 22.

“To be fair we defended really well but we fell off a couple of tackles out wide and you could see Ireland grow in confidence.”
