Leinster have already qualified for the knockout stages of the European Rugby Champions Cup. They top Pool 3 by two points and their final fixture sees them travel to bottom-placed Aviron Bayonne. Read our match prediction below.

The Irish club are three points clear of second-placed Harlequins and five ahead of Stormers in third. A top two finish guarantees a team playing at home in the last 16. Leinster have a much better points difference than Stormers so it's looking good for a home tie.

Last weekend saw Leinster win at home to Stade Rochelais but only by a single point. It was their eighth successive victory. 

All three of their pool games have been won. Their only away fixture produced a 23-15 win at Leicester Tigers.

Aviron Bayonne are yet to earn a point and have a points difference of -106.

Only 45 points have been scored by the Top 14 side in their three pool matches.

They were beaten 57-14 at Leicester last weekend. The Tigers are fifth in the pool, five points ahead of Bayonne. Even a win and a bonus point for the French club is unlikely to see them escape finishing bottom due to that appalling points difference.

We tip Leinster to win this match on a 17.5 handicap.

Our Aviron Bayonne vs Leinster Prediction

Leinster have already ensured they will be playing in the knockout stages but will want to finish in the top two. That will mean a home tie for the Irish club in the last 16 and a high seeding if they win this pool.

That looks very likely at they travel to Aviron Bayonne who need a big win here. Considering Bayonne have only scored 45 points in three pool games that would be a massive shock. Our Aviron Bayonne v Leinster prediction is Leinster wins on a -17.5 handicap.

Prediction :
