Chris Coleman has promised Wales will learn the lessons of their defeat to England in their Euro 2016 showdown with Northern Ireland.

Just a day after the United Kingdom took the momentous decision to leave the European Union, two British sides will go head to head in the last 16 of the European Championship in Paris.

It is the second time Wales have met British opposition at this tournament following their 2-1 defeat to England in the group stages.

Wales recovered from that setback to top Group B and get the reward of playing one of the best third-placed teams, but that defeat still rankles with manager Coleman as he believes his side were caught up in the emotion of playing fellow British opponents.

"What we did in the last experience against a team from Great Britain, we fought well and stood our corner out of possession," said Coleman at his pre-match press conference.

"But when we had the ball we never got near our capabilities because we got caught up in a game with the emotional side of a derby game.

"That's what we needed to put right in the game against Russia, which we did, and now we've got to take the emotion out of playing Northern Ireland.

"When you get too emotional - and don't get me wrong you need a bit of emotion - then your plans go out of the window.

"We never really showed England what we were capable of with the ball, and the message for us is to stick to our game plan and do what we're good at."

The two sides met as recently as March when Northern Ireland were leading a Cardiff friendly 1-0 until the final moments.

But Wales, who were without key players Gareth Bale and Aaron Ramsey because of injury on the night, won a late penalty which Simon Church converted.

Coleman said the friendly was a worthwhile exercise, especially with the two sides meeting three months on, but insisted it would have no bearing on the outcome at the Parc des Princes.

"It was a good game for us," said Coleman.

"They were very strong and physical, very well organised and dangerous from set-pieces.

"We played well on the night but, of course, Gareth and Aaron make a difference and that result will count for nothing tomorrow.

"This is tournament football and both teams find themselves in the position where they've earned respect and attention.

"It will be about who handles that spotlight the best and who performs best under that pressure."

Northern Ireland boss Michael O'Neill wants his players to feed off the hype surrounding the last-16 tie.

"I want my team to play with loads of emotion; I want them to fully understand the significance of the game," he said.

"When you look at our performances, especially in the latter two games, you couldn't question the effort of the team from the first minute to the last minute.

"I don't think you can play without emotion. I don't expect my team to and I think it will be a big factor in the game tomorrow night.

"It will be like a cup tie, but whether it's like a Premier League team going to a Championship team...that's irrelevant.

"The main importance is that we make it a cup tie. We were bottom of the simulation rankings and we're proud of that. We have an English referee (Martin Atkinson) and we want everything that is good about the British game in it.

"We want to do our best within the rules and we expect a good old-fashioned British game tomorrow night."
