McGuinness says six subs needed under new rulespublished at 13:46 2 February

Jim McGuinness' Donegal side beat Dublin 0-20 to 0-16 in what was the Football League opener after the postponement of last weekend's scheduled contest in Kerry
Jim McGuinness says the attrition brought on players by the new football rules should lead to the amount of substitutes being increased from five to six.
McGuinness pointed to the three Dublin players forced off by hamstring injuries in Saturday's Allianz League Division One contest at Ballybofey as his Donegal side clinched a 0-20 to 0-16 victory in what was their opening game following the postponement of last weekend's scheduled game in Kerry.
"I feel for Dublin. They lost three players with hamstrings. I think that's definitely something that has to be looked at," said McGuinness of the new rules.
"Peadar Mogan would be one of our fitter lads and he was really struggling at the end and we had the five subs on and we couldn't get him off.
"In the first document the FRC [Football Review Committee] put out, there were six subs and I saw that and thought that would be good and would take a bit of pressure off."
Otherwise, McGuinness was reasonably content with how the new rules worked although he did admit his disappointment at his team being caught out on one occasion as they didn't keep three players in the opposition half.
Murphy would have played under old rules
McGuinness resisted the temptation to give Michael Murphy his inter-county return, saying that the view was that the Glenswilly man wasn't yet quite ready for the rigours of a high-octane contest under the new rules.
"Probably if we were playing under the old rules, Michael would have been on tonight but we have to be very careful to make sure we're hitting all the targets before we decide to put him into action."
Despite his side's victory, McGuinness wasn't entirely happy with the display, where Daire O Baoill top-scored by notching six first-half points.
"We've a lot to work on. We gave a lot of silly passes away. We lost the ball in transitional moments and we kicked ourselves out of it in the first half.
"We should have had a lot more scores on the board but the big positive would be the resolve that they showed in the second half. They kept the ball better and found a way to keep tagging on scores."
Donegal's postponed game with Kerry has been rescheduled for next weekend which mean McGuinness' side are going to be in action over five straight weekends.
