It's time for Planet Rugby's weekly round-up of who has their name in lights at the moment…and who is making the headlines for the wrong reasons.
They're on fire!
Racing and Saracens: Big winners over the weekend as they beat Scarlets 64-14 and Ulster 33-17 respectively. These two, along with Leicester, have impressed throughout the pool stage and with Dan Carter and Owen Farrell leading excellent packs and backlines, they seem to have the whole package. Home quarter-finals await.
Enisei-STM: Stunner. The Russians picked up a second win in the Challenge Cup pool stage after shocking Newcastle 24-7. This came on the back of beating Brive in Round 3 but Saturday's victory was more impressive, especially with the weather not playing as much as a factor. A trip to Connacht concludes their pool campaign.
Harry Mallinder: Son of Northampton boss Jim, young Harry was the hero for Saints as his winning try against Glasgow snatched victory for the Premiership side to keep their European hopes alive. Impressive from the 19-year-old.
Munster and Leinster: Bouncing back from disappointing campaigns so far in Europe, Munster got the better of Stade Francais 26-13 on Friday before Leinster's youngsters beat Bath 25-11. The big ask from their passionate fans is now whether the two teams can maintain this kind of form in the second half of the season.
Alun Wyn Jones, Justin Tipuric and Sam Underhill: Sam Davies should get credit for his maturity too but the efforts of these three players at the breakdown and in defence deserves a ton of praise. Jones is one of the world's best locks, Tipuric a turnover menace and as for Underhill… what a special player he looks to be at just 19.
Wasps and Cardiff Blues: Losers who deserved more for their efforts. Guy Thompson's try looked to have secured a famous win in Toulon for Wasps before the European champions rallied. Blues meanwhile were down and out at 0-28 away to Harlequins before a remarkable second half, which they won 26-6, only to lose out at the final whistle. Hard luck.
Someone get these guys a warm cup of soup!
Toulouse: Dire. Bottom of their pool after their fourth defeat came at the hands of Oyonnax. How the mighty have fallen.
Bath: Second best in Dublin, sticking a fork in Bath's European hopes early with one round to go. What a slippery slope last season's Premiership finalists are currently on. This was poor against a weakened Leinster side, and Bath's indiscipline was a major culprit.
Treviso: It's time to ask whether Treviso will win a single game this season. Make that five out of five losses in Europe to go with 12 from 12 in the PRO12. New head coach Kieran Crowley has his work cut out after they were well beaten by Leicester at Welford Road.
Agen and Pau: A grand total of three points combined from these two teams in the Challenge Cup losses to Edinburgh and Sale Sharks. We're not saying they didn't try, but…
Vito Kolelishvili: Clermont flanker Kolelishvili could be cited after he was penalised for pushing referee Wayne Barnes in his team's loss to the Ospreys on Friday. The Georgian wasn't carded by Barnes at the time but was later sin-binned after he was involved in a scrap with Ospreys lock Alun Wyn Jones. A hot-headed performance from the player.
