The verdict was given after the youngster starred in Wales’ emphatic 6-1 victory over Montenegro in their Women’s World Cup qualifying campaign.
Griffiths scored twice in an eye-catching performance at Parc y Scarlets in Llanelli as Wales powered to their biggest win of the year and moved to the top of Group B1 on goal difference, ahead of rivals the Czech Republic.
While the scoreline reflected a dominant night for Wilkinson’s side, the emergence of the young Manchester United player – currently on loan at Sunderland AFC Women – proved the stand-out storyline.
"She's got it all," said a satisfied Wilkinson.
"And she's far from the finished product, which is very exciting for all Welsh people I'd imagine."

Wales had begun their qualifying campaign just days earlier with a tense 2-2 draw away in the Czech Republic, where a stoppage-time equaliser from Elise Hughes rescued a valuable point.
Back on home soil, however, the contest proved far more comfortable.
Wales quickly found rhythm and confidence in attack, with Griffiths and Hannah Cain both helping themselves to two goals as the hosts overwhelmed a Montenegro side ranked 84th in the world – 52 places below Wales in the FIFA standings.
The result ensured Wilkinson’s team maintained an unbeaten start to 2026 and strengthened their early position in the group.

For Wilkinson, the performance of Griffiths was particularly encouraging because it demonstrated how early promise can help fill the void of the post-Jess Fishlock era.
"I think it's a testament to the team that when a young player like Mared comes through our pathway, she feels comfortable to play with the freedom which you see," added Wilkinson.
"She plays with a creativity that you don't see that often with young players coming up to the senior team because they're too nervous to express themselves. It's really nice to see."

The Canadian coach believes Griffiths’ rise is also proof that Wales’ development structures are producing a new generation capable of competing at international level.
"We've been excited about Mared for a while now and we have a couple of young players coming through who are real talents," the Wales boss added.
"I think it's a testament to our youth coaches, but also our academies in the north and the south and what they're producing.
"Mared's our first real product of testing our pathway. I know there are others."
Alongside Griffiths, Cain also played a leading role in the victory.
The forward continued her excellent form in the qualifiers with another two-goal display, adding to the equaliser she had scored earlier in the week against the Czechs.
“I’m really happy and chuffed to get on the scoresheet again,” Cain said.
“It was a positive performance with loads of goals and hopefully we take that into next camp now.
“It’s been a positive week overall. We obviously would have liked to have got the win in the first game, but we know it’s a difficult place to go away to. It’s one that we take and move forward to the next game now with momentum.
“I think, as Haz [Angharad James] said in her press conference this week, we wanted to get five wins. Now we’ve got four more to tick off, so we go again.”
Cain’s performance also earned her the player-of-the-match award for the second game running after she had been recognised for her display in the draw against Czechia.
“I’m really happy and I’m really proud,” she added.
“It could have been anyone tonight as they were all outstanding, so it makes it extra special that I was the player to get it. But it’s a team performance and I won’t have got the goals without my teammates.
“I love scoring and I want to score all the time. When you score for you country it’s an amazing feeling and it’s also a lot more special. I’m just happy to get on the scoresheet and to help the team once again.”
Wales’ attacking dominance was clear throughout the evening.
Griffiths and Cain both found space repeatedly in Montenegro’s defence, while experienced figures Rachel Rowe and Sophie Ingle also added their names to the scoresheet.
Montenegro managed a second-half consolation through Armisa Kuc, denying Wales what would have been their first clean sheet in 17 matches, but the goal did little to dampen the celebratory mood among the home supporters.
More than 4,500 fans packed into Parc y Scarlets to watch Wales play an international in Llanelli for the first time in almost two years.
