It all start with Leinster hosting Toulon on Friday in the round of 16 weekend.
Leinster have won the tournament four times and Toulon done it three times but all that doe snot matter when the two teams run out on the RDS Arena.
Leister will go into the match as huge favourites who just won another Guinness PRO14 trophy. Last two years Leinster has been knocked out by Saracens in the playoffs.
History will show that Toulon have a 100% winning record against Leinster winning against them all four times they have met before.
Toulon will be no pushover this Friday, they have a powerful side with big blokes and like to play an expansive style of rugby. This will stretch Leinster defence which will have to be on point.
Although Toulon have a great record against the Irish side but since that last loss in 2015 the Irish side have won 17 out of their last 18 matches in the Champions Cup.
Everything shows that this will be a cracking match come Friday.
Johnny Sexton will start for his club on Friday as well as captaining the side against Toulon.
James Lowe is also back in the side this week. Hugo Keenan will be at fullback again with Larmour on the right wing.
In the midfield Robbie Henshaw will join Rory O’Loughlin with McGrath that will be Sexton partner at number nine.
In the pack the front row of Cain Healy, Ronan Kelleher and Tadhg Furlong will start with Devin Toner and Ryan Baird in the second row.
The same loose-trio that played against Munster last week was selected for this one against Toulon.
For Toulon, Gabin Villière has returned from injury and will start the match for the French outfit.
With Nonu suspended, Rudi Wulf will get the starting jumper this week. He will join Julien Heriteau in the midfield.
Paia’aua will move into the number ten spot with Carbonel not available. Baptiste Serin will partner with him at halfback.
In the front row we see Charles Ollivon, Swan Rebbadj and Romain Taofifenua all returning to the starting XV.
The match will be live on SuperSport at 18:25 on Friday so do not miss this one.
