The Cardiff Blues director of rugby has seen three other Welsh caps extended their stays at the Arms Park recently and now has another to count in for his first complete season back in charge at the Welsh capital club in the 2021-22 campaign.
“We’ve all seen how devastating Tomos can be with the ball in hand. He certainly has that X-Factor and is a worry for defences,” said Young.
“His all round game is also very good and, even though he has been frustrated by injuries during the last year, he is only going to get better and better given a run of games.
“Retaining his services was really important for us and we have now managed to keep all the players we wanted. That is testament to the club after what has been a difficult year.”
The 26-year-old Williams won 20 caps over two seasons at Under-20 level for Wales and made his World Sevens Series debut at 19.
The Treorchy-product made his Blues debut against Munster in 2013 – the same team he scored two tries against last weekend in the Rainbow Cup.
He reached 100 appearances for the Blues this year and has notched 22 Welsh caps.
“We’ve got a lot of exciting talent at the Blues and a lot of potential moving forward, especially with Dai back in charge and Matt Sherratt coming back to the club,” said Williams.
“I want to be a part of that and it would be great to help this club challenge for more silverware.
“I’m very grateful to be staying here and I’m looking forward to getting back to the Arms Park with crowds in attendance in the near future.”
