HADLEIGH Parkes says Wales have to sort out their discipline if they want to play a daring style of rugby.

Warren Gatland’s men will finish the Six Nations with home games against Italy and France, fixtures that they are expected to win.

Title hopes were ended by defeat in Dublin last weekend when Wales left it too late, coming to life in the final quarter to score super tries through flanker Aaron Shingler and wing Steff Evans.

However, Ireland’s power game secured the spoils with centre Parkes lamenting their hosts’ dominance of possession; getting on the wrong side of referee Glen Jackson meant that Wales were unable to play a high-tempo game.

“We have made no bones about our aim to play more of an expansive game and you can tell from the three tries that we scored in Ireland that it’s kind of working,” said the Scarlets back.

“We did make some opportunities but we just gave Ireland too many penalties and got starved of possession that they capitalised on.

“Ireland just kept coming and coming, playing off nine with some big boys that make good inroads.

“We are disappointed because we did have a chance to win but we didn’t start as well as we wanted to and that cost us.

“We are disappointed that we didn’t look after the ball and we gave Ireland a lot of penalties. They are too good a side to allow that.

“We could have won it at the end and there are positives – we didn’t spend too much time in their 22 but managed to score three good tries.

“When we did hold onto the ball we looked pretty good with nice shape and opportunities going wide.”

A Six Nations campaign is an unexpected bonus for Parkes, who qualified for Wales on residency in December.

The New Zealander started against South Africa in the autumn and has slotted into midfield against the Scots, English and Irish.

“I am enjoying it, it has been an awesome opportunity. I never thought that this would happen so I am very happy to have been given the chance,” he said.

“The Six Nations is an awesome competition. The fans are so good and a lot travel, while there is so much history involved in it. There is pretty good rugby being played as well.

“We want to finish strongly now with two home games, we have to put pressure on ourselves to win them and then hopefully we can finish in the top three.

“We have made some good yards this season and just need to keep moving forward.

“These games have been hard away from home but we still had opportunities to win if the bounce of the ball or a couple of things had gone our way.

“Sometimes you need a bit of luck on your side. Unfortunately we were on the wrong side of things against England and Ireland but these last two games give us the chance to build some momentum.”

Meanwhile, Wales fly-half Dan Biggar has been urged to stop questioning officials so frequently by legendary flanker Martyn Williams.

The Ospreys ace was frequently in the ear of referee Glen Jackson in the loss to the Irish.

“It is something he has to take out of his game,” Williams told BBC Scrum V.

“Senior players have to say ‘50-50 calls might go to the other team because you constantly complain’.

“He is one of the senior players. They have to pull him aside and say ‘Dan you are killing us here’.

“Referees are human and if someone is into you all the time you don’t get the calls.

“For 60 minutes of that game he did not stop complaining.

“At this level that is unacceptable, you can’t be complaining all the time. If he is going to penalise Ireland he is going to penalise Ireland, whether you throw your arms in the air or not.”

Lion Biggar returned from injury against the Irish, taking Rhys Patchell’s place after the in-form Scarlet got the nod for Scotland and England, but Gatland is mulling over changes for Italy with Gareth Anscombe in contention for a rare start at 10.
