We should be in store for a cracker today.

Some pre-match reading to get you in the mood as we await throw-in:

• Have Galway already peaked, the impact of club games on Dublin’s build-up and the last ever U21 final

• All-Ireland dual winner, Meehan-Armstrong goals and James Horan’s hurling role

How is it going to go?

• Poll: What do you think will be the outcome of Dublin and Galway’s All-Ireland U21 final clash?

All set for throw-in in Tullamore.

And we’re under way.
