'I’m going for Leinster. As a former Munster player and supporter now it’s hard'

Three experts give their thoughts - and verdicts - on Saturday's Heineken Champions Cup final between Leinster and La Rochelle

Locked in: La Rochelle head coach Ronan O'Gara along with Donnacha Ryan in Marseille on Friday.

There won’t be any more determined man in Europe than Ronan O’Gara this weekend as he tries to bring the Heineken Champions Cup home to La Rochelle. As if the sight of a Leinster jersey wasn’t enough to fire him up, Johnny Sexton will be leading the charge for the four time champions. Old rivalries die hard and I’d love to listen in to Rog’s team talk before the game. I played with and against both of Rog and Johnny and they are like two peas in a pod. Both are incredibly confident, it’s their way or the highway, they are great tacticians and they both have great composure. Of course, one of them will be on the sidelines and one on the pitch, although I’ll bet Rog kicks every ball and catches every pass over the 80 minutes.
