The scary thing? Leinster capable of getting better

The fact that Leinster were made fight much harder than had been anticipated to prevail in a pulsating Champions Cup final that went right down to the last kick off the game will, you feel, stand to their exciting young squad in the years to come.

For some in their ranks, scaling the heights of the club and international game in the infancy of their careers, they must be wondering what all the fuss is about.

If the Grand Slam success over England was delivered without undue stress, having to fight for every inch to add a Champions Cup medal to what is shaping up to be an unforgettable season will, you feel, stand even more to their development over the months and years to come.
