Paul Flynn has tipped Tyrone and Donegal to offer a potent threat to the likes of Dublin and Kerry when the All-Ireland championship comes around.

Speaking on RTÉ's Game On ahead of this Sunday's Allianz League Division 1 South clash between his former Dublin team-mates and Kerry, the six-time All-Ireland winner suggested the Ulster duo had the tools to make a mark this year.

"I think Tyrone are going to be very strong this year and I always felt that they had the conditioning and I always questioned their shot selection and their conversion rate up front," he said.

"But this year now they've got McKenna, McShane - two of arguably the better forwards in the country - and a couple of the other young lads coming in too which are going to offer a lot."

"I think Donegal are very strong. Last weekend to see McBrearty and Murphy to play so well is only good for them and the range of scorers that they have as well. All six of their forwards scored which is always a good sign that they're playing well as a team.

"But the one thing this year is that we're probably not going to see all those teams playing against one another in the championship and that to me is disappointing. I think we should be set up like that for design and not have a Dublin-Kerry game just by default.

"We want to see that game, people want to see that game and last year it was disappointing that we didn't get to see it in the championship."

Turning his attention to Sunday's mouthwatering clash between Dublin and Kerry, the form David Clifford showed last weekend against Galway bodes well for the Kingdom but Flynn feels they have defensive concerns to focus on.

"It's going to be a cracker. The questions I have about Kerry are still going to be defensively," he said.

"I look at their team defensively, they've got good players there but I just don't see the cohesion. I haven't seen it yet. They have been trying last week some new structures at the back but I'd like to see that really being tested against Dublin."
