Liverpool and Wales midfielder Harry Wilson has flourished during his Championship loan spell, according to Welsh coach Osian Roberts.

Wilson who hails from Corwen, has found starting opportunities at Anfield limited and enjoyed a successful loan spell with Hull City, where he netted seven goals in 13 appearances last term.

Welsh manager Ryan Giggs and assistant Roberts ran the rule over Wilson at Monday's open training session in Wrexham ahead of their friendly with Mexico.

The 21-year-old attacker now looks set to win his fourth international cap following his impressive scoring return to the side at March's China Cup.

Those appearances came four years after he made his debut under Chris Coleman, becoming the youngest ever capped Welshman at the age of 16 years and 207 days old.

Despite that protracted break in international action, assistant coach Roberts insists Wilson's recall has coincided with regular first team action at club level.

He said: "I wouldn't say that Harry was in the wilderness in that time. I think it's been part of his development and the way he has developed with Liverpool throughout the youth teams until the under 23s has been excellent.

"But of course at the same time there's competition for places and other players perhaps playing in first team environments have probably pushed on as well.

"But since he moved out on loan halfway through the season we've certainly seen how he's kicked on in that competitive environment that we like our young players to be involved in.

"We've seen a difference, in my opinion, and we're delighted with his progress and now we're looking for more from him."

The Welsh will be without the talismanic Gareth Bale for Tuesday's game, with fellow regulars James Chester and Joe Allen also unavailable.

Giggs' initial 32-man squad included nine uncapped players ahead of Tuesday's clash with the Mexicans in Pasadena, California.

And Roberts has urged any young player selected for the friendly to seize the opportunity.

He said: "It's natural that we'll have uncapped players involved.

"We're in a period of transition and we've got this younger generation of players who are coming through. They're excelling, they're exciting and it's an opportunity for people to put their name forward and try to get that shirt.

"We want that competition for places. We've done well over the last few years, but at the same time we want to go from strength to strength and the best way is build that competition for places and we feel we're getting there.

"Mexico are a top team, a quality side. We had a fantastic game against them six years ago in New York and it was one of the catalysts for the progress and the development that followed and helped us achieve what we did at the Euros.

"So if this has the same effect, we'll be delighted.

"It' s certainly going to be a big test for us and the type that we need prior to the competitive games.

"It's going to be an interesting week, but I think it's the perfect game for us at this stage of the year."
