A group of primary school children have written positive tweets to Liam Williams after the rugby player received online abuse following Wales' Six Nations clash with France on Saturday.
Williams received a yellow card which reduced Wales to 13 men seven minutes from time.
The WRU shared a selection of screenshots Liam Williams received after the game and said players wanted to highlight the abuse and 'drive the call for change.'
Pupils at Penywaun Primary in Aberdare were tasked with writing positive tweets to Williams and to call out online abuse.
Student Blake wrote, "You did well on Saturday, keep it up. Just ignore those mean comments!"
"And please don't be sad or upset. You are a good player and that's the end of the story.
"One of them called you a wet wipe and that's not nice. So please play more rugby. The only thing that matters is you're happy."
Another pupil wrote, "Sorry you had to listen to those mean people, they just don't understand how hard it is to be a rugby player.
"You are my favourite player in the world, at least you can still win the Six Nations, good luck on everything!"
The tweet, which has been liked almost 2,000 times, saw Liam Williams respond, thanking the class for their kind words.
Teacher Courtney Pritchard told ITV News, "It's really nice to show children that social media can be used in a positive way."
She added, "In school, we spend a lot of time showing children the dangers of the internet so it's really nice to be able to show them to show them actually, you can use it in a positive way.
"I don't quite think the children realise quite how far the tweet has gone yet so I am planning a little lesson around that!"
