As expected, Dublin marched on to a sixth consecutive Leinster title success with an emphatic win over Westmeath at Croke Park on Sunday.
They are three games away from retaining their All-Ireland crown, with many now asking who can stop them in their quest to lift Sam Maguire on 18 September.

"I think O'Sullivan is the best sweeper we have in the country at the moment and he's playing it brilliantly," said the former Kerry star.
"He'll regularly coast his way back and protect the full-back line.
"For teams to have a chance against Dublin, you have to make him do things he doesn't want to do. You have to have your homework done on him.
"If you can take O'Sullivan out of position, he will leave space behind and Westmeath did manage to break through and create scoring chances."
As if keeping tabs on O'Sullivan wasn't enough, Ó Sé also pointed out the importance of Stephen Cluxton and Brian Fenton in the Dublin gameplan and added that opposition have "an awful lot of homework to do" if they are derail Jim Gavin's side.
