Stade Franšais host Montpellier in a clash between two in-form sides riding a wave of confidence at Stade Jean-Bouin on Friday.
Something has to give.
Like their hosts on Friday, Montpellier are always strong at home but have learnt to produce the good on the road this season, so we're in for a good contest.
Last week's 40-point win over giants Clermont was the most impressive result of the season - even more so than their 25-0 drubbing of Toulouse - and underlined Montpellier's credentials as genuine title contenders.
The hosts are also in great form, coming off the back of three straight wins and are unbeaten at home this term. The Parisians have won eight and draw one in the last nine clashes between these sides in the French capital.
Stade have made four changes to the side that beat Oyonnax last week, all in the pack as prop Heinke van der Merwe, hooker Laurent Sempere, lock Gerhard Mostert and loose forward Pierre Rabadan all return to the starting XV.
Montpellier have lined up the same starting team that thrashed Clermont last week.
