New Harlequins centre Jamie Roberts enjoyed his debut for the club as he scored a try in a convincing win over Calvisano.
Roberts signed for the Premiership side from Racing 92, but has spent his time since the Rugby World Cup with Wales playing for Cambridge University while studying for his part-time masters degree.
The 29-year-old Test star appeared to relish the "unique" experience of playing in the Varsity match for Cambridge against Oxford, but is now focused on giving his all for his new club.
"I was pretty excited to get out there for my first game for Harlequins. It's been a long time coming, I signed for Quins at the start of the year and I finally got the chance to wear the quarters at the Stoop in front of a good crowd," Roberts told the EPC Rugby website.
"It was cool to get back into Europe and play with this good bunch of boys, the first week has been amazing and hopefully I've put my hand up for selection next week, it will be a huge match at Twickenham.
"It was a big step-up in intensity, the Varsity match is unique for the students, it's a one-off cup final every year. But this is professional rugby, it's a different ball game, every one is doing their job and you can see the structure of the team.
"Student rugby is a bit of a free-for-all, but it's great to get back into the professional environment and I've just got to keep working hard to improve myself as a player.
"We've got Christmas day off, we train on Christmas Eve and Boxing Day, the schedule is pretty hectic. I'll head back to Cardiff to see the family over Christmas and then I'll be raring to go next weekend."
