Dublin boss wary of Waterford threat

Dublin U21 boss Tommy Lyons has made it clear that Waterford are the form team coming into Sunday's All-Ireland semi-final football clash in Thurles.

Dublin haven't played a game since April 27 when they won the Leinster final while Waterford defeated both Cork and Kerry to get this far and are riding high right now.

Lyons said: "They have some excellent footballers.

"A game like this is won and lost by the players' attitude, so it has to be right. We have been well warned because their attitude is obviously very good right now."
