When Johan Mulder arrived at Cardiff Rugby in 2024, few expected the South African scrum-half to become such an important figure so quickly.
Signed with little fanfare from Currie Cup side Griquas, Mulder initially looked destined to provide depth rather than lead Cardiff’s push towards the United Rugby Championship play-offs.
Instead, the 26-year-old has emerged as one of the club’s most reliable performers across the past two seasons, helping guide Cardiff into one of the biggest games in their recent history.
A victory over Stormers at the Arms Park on Friday night would secure Cardiff a first-ever URC play-off appearance.
For Mulder, achieving that milestone against opposition from his homeland would carry extra significance.
Cardiff move came as a surprise
Born in Pretoria, Mulder progressed through the Bulls pathway before continuing his development with Griquas and briefly featuring for the Lions in the Challenge Cup.
A move to Wales was never part of the immediate plan.
“I was actually shocked when they showed interest in me,” Mulder admitted.
“I didn’t think a team like that would even consider me.”
The chance to join Cardiff quickly became impossible to ignore.
“It’s a really prestigious club with a lot of history. There are legends of the game that have played here. So it was an easy choice for me. Coming here was a massive honour.”
Welsh rugby has helped evolve his game
Mulder believes the move has accelerated his development as a player. In particular, adapting from South African conditions to the tactical demands of northern hemisphere rugby.
“In South Africa, it’s mostly sunshine, it’s hot,” he said.
“Coming here, getting used to wind, rain, new coaching systems and different styles of play, it just develops your game.”
The scrum-half admits his early instinct was to play with constant attacking ambition. But, the URC has forced him to refine his control and game management.
“At the beginning of last season, I maybe forced a few things, but I feel calmer and more confident now.
“I was used to just running the ball from everywhere, so I’ve had to adapt to a lot more of a kicking game.”
Mulder added that the margin for error in the competition is far smaller.
“If you make a mistake over here, the other teams are a lot better at capitalising on that, so it’s a lot more about control.”
Injury setback failed to halt momentum
A broken jaw suffered in training last November temporarily interrupted his progress. However, Mulder has become a near-constant presence in Cardiff’s matchday squads since returning.
His performances have added balance to Cardiff’s attack, while his tactical kicking have stood out during the club’s push towards the top eight.
“I think I have been doing well so far, but I still feel I have a lot more to give and a lot more improvement to do,” he said.
Cardiff’s improvement this season has mirrored Mulder’s own rise in confidence.
After years spent battling inconsistency, the Welsh side now enter the final weekend with genuine control over their own destiny.
Bigger moments on and off the field
Away from rugby, Mulder’s life in Wales changed forever earlier this year with the birth of his daughter, Lana.
“It was probably the best feeling in my life so far,” he said.
“It’s a new journey and I’m really excited for it.”
Now another potentially defining moment awaits on Friday night.
With a packed Arms Park expected and Cardiff knowing a win guarantees a play-off place, the occasion could become one of the biggest the stadium has hosted in recent years.
“I think the vibe will be amazing,” Mulder said.
“Running out at the Arms Park with a full crowd, I’m really looking forward to it.”
For a player who once doubted whether a club like Cardiff would even look his way, helping them make URC history would represent quite the full-circle moment.
