Watch: 18-year-old French fullback scores the youngest ever European hat-trick

After playing for France under-20's last July a month after his 18th birthday, Louis Bielle-Biarrey has got off to a storming start to his pro career with Bordeaux Begles.

After making his club debut a week ago and receiving a ghastly initiation haircut in the process, Bielle-Biarrey became the youngest player to score a hat-trick in the Champions Cup after his three try outing against Scarlets.

In just his second outing, Bielle-Biarrey cut the Welsh to pieces with great supporting lines on the way to three tries as Bordeaux went on to a 45-10 win.

His first came after a half-break from Argentinian pocket rocket Santiago Cordero, who linked up with his 15 in the backfield. Bielle-Biarrey put a big right foot step on the last man to score under the posts.

His second came from a sweeping wide movement and a brilliant short-ball from flyhalf Mathieu Jalibert to put him into a tight gap. After a juggle, the young fullback regained possession and slide over for his brace.

His third came with seven minutes to go with the result well and truly decided, he was able to waltz over out wide after hands down the short side from five metres out finished the hat-trick.
