Leinster face off against La Rochelle this Sunday (kick-off, 4.15pm), as they look to end a three game losing streak against the reigning Champions Cup holders.
Leinster's struggles against the Ronan O'Gara coached side have been defined by the game changing performances of Aussie lock Will Skelton, who stands at 6ft 8in and weighs in at over 21 stone.
Sam Warburton Offers Up His Views On Leinster Vs La Rochelle
Size matters at this level of rugby and it is an area that Leinster have struggled with, as their pack does not posses the enormous units that La Rochelle have in spades.
In an interview with RugbyPass, Wales legend Sam Warburton still harbours doubts over Leinster's ability to deal with the sheer size of La Rochelle.
They always play phenomenal rugby in the pools but they come unstuck physically when they play a La Rochelle or, in years gone by, a Saracens.
The only place you can question Leinster is physicality and the same question has come to the Ireland team as well. This will be fascinating to see.

“We know how good Leinster are going to be from an attacking perspective," Warburton added.
"They are great in defence but if La Rochelle just want to carry off nine and maul and play a kicking game – and you imagine they will be very astutely coached by Ronan O’Gara – that is the one big question mark that hangs over Leinster.
"We are going to find that out a lot earlier this year than in previous years gone by. That is what is fascinating about that game.”
