Some eyebrows were raised when French referee Jerome Garces was named as the match referee for Saturday’s Heineken Champions Cup final, but Leinster will be hoping to keep on his good side at St James’ Park.

The reigning champions meet arguably the in-form team in Europe in Saracens who will be looking to deny Leo Cullen’s side a fifth European Cup.

Garces will oversee the action having being selected ahead of the likes of Wayne Barnes and Nigel Owens.

He came under criticism in some quarters for his handling of the breakdown in the semi-final between Sarries and Munster in a game where he awarded 18 penalties.

Ryan has played in all eight games in the run to the final and will be preparing to lock horns with Maro Itoje in the second row, but knows they must also do their homework on the man who officiates "slightly different to some refs".

"We look at the referee coming into every game," he told RTÉ Sport.

"I don’t think we ever over-analyse the officials. If we get our stuff right and paint the right pictures, the rest will look after itself. If we get our attacks and breakdown right, it won’t be a problem hopefully."

The English powerhouse is stacked with Lions quality and while the Irish second row concedes their work at the breakdown is a strength, it isn’t he contends their main source of turnover ball.

"Saracens get most of their turnovers not from on the ground, but from reefs, from big dominant tackles as opposed to poaches.

"That’s why we are going to need to be direct this week because if they are dominating us on the gainline, we can forget about who is refereeing us."
