Blues have the firepower to reap revenge


and not what can happen, they could come a cropper against a fast-acting attacking force.

Defence coach Kurt McQuilkin will emphasise the importance of organisation, timing, trust, aggression and concentration in what is sure to be a high-octane atmosphere, despite the vastness of Twickenham.

From there, Leinster's offensive style of defence can drive the ball carriers into reverse gear, leading to slow ball that can be turned over quickly for the quicksilver countering of Isa Nacewa and Rob Kearney.

The Exiles have a lineout to compare with the best in the competition, with Nick Kennedy a super athlete in the air and Bob Casey an immovable force closer to the ground.

The use of Leinster's third and fourth jumpers Jamie Heaslip and Kevin McLaughlin anywhere along the line from front to back can give John Fogarty the options he needs to stay away from the Exile's main snafflers.

Out-half Jonathan Sexton has so much to offer as a one-out runner. His physicality and deceptive stride will keep the opposition backrow honest all day along, creating vital space on the outside.

The rejuvenation of Shane Horgan and elegance of Nacewa provide a twin threat around the edges, with Robert Kearney showing greater ingenuity on the counter than he did this time last year.

Leinster have the grit of their forwards inside, the weapons on the outside and the means of linking one to the other at half-back and in the midfield to make it five wins on the spin.

p Verdict: Leinster
