Donegal steamrolled Kerry in the Ballybofey snow yesterday, for a defeat that leaves the Kingdom staring relegation to Division Two firmly in the face.
Michael Murphy scored 1-5 for Donegal as the All-Ireland champions chalked up an impressive win.
Just five minutes in, Ross Wherity won a penalty when he was bundled over by Johnny Buckley. Murphy had missed against Tyrone last weekend, but there was no repeat this time.
They led by six when Patrick McBrearty curled over in the ninth minute and a brace of classy points by Murphy had Donegal 1-5 to 0-3 at the break.
Kerry's task was steeper still when Tomos O Se was red carded five minutes into the second half.
By the time Darran O'Sullivan ended a barren 28-minute spell for Kerry, Donegal were nine up and in control.
Murphy's brilliance endured for Donegal, whose bursts from deep were a key factor in the contest.
Four minutes from the end, Kerry had a golden chance to bring a little respectability back to their total, but Paul Durcan brilliantly saved Kieran O'Leary's penalty.
Murphy tapped over a late free to ensure some searching questions in the Kingdom this week.
Scorers: Donegal: M Murphy 1-5 (1pen, 2f), L McLoone 0-2, C McFadden (f), P McBrearty, R Bradley, N Gallagher, R Kavanagh 0-1 each.
Kerry: J Buckley 0-3 (1f), T O Se, D O'Sullivan, E Brosnan 0-1 each.
