PREVIEWS: Ulster and Munster SF championships

ULSTER SFC: Semi-finalDerry v Donegal, Clones, 2.40 (Network 2)Ten years ago Eamonn Coleman and Mickey Moran were directing operations for Derry on the road that would lead to the 1993 All-Ireland. Much troubled water has flowed under the bridge since and tomorrow they come face to face for the first time in championship.

Under Moran, Donegal have been developing nicely over the past two years and this season have hit a good vein of form. Their fluid, mobile game is directed towards supplying a lively attack and they've been getting it right so far, overwhelming Cavan and Down. Brendan Devenney and Adrian Sweeney have been attracting most of the attention but Brian Roper and Michael Hegarty are providing good support.

Against that Derry have had a sluggish year, effectively taking a rain check for the National League before preparing for the championship. The first outing was fairly uninformative with Antrim a little lucky to get knocked for 10 given the amount of wides Derry kicked and some good saves from Seán McGreevy. Nonetheless they still have the game to discomfit Donegal whose short-passing tactics can be disrupted by physical presence. A demoralised Down allowed them far too much room in which to launch attacks.

Derry's cover will be more claustrophobic and Anthony Tohill and Fergal Doherty will expect to dominate in the air although John Gildea and Jimmy McGuinness have the edge in mobility and on the break.

Enda Muldoon was a welcome return the last day after a long lay-off and with him back the attack has a formidable look with Gavin Diamond in good form although there remain question marks about its penetrative capabilities at the highest level. They should have enough for the job in hand.

MUNSTER SFC: Semi-final replay

Clare v Tipperary, Gaelic Grounds, 4.0

Intriguing rematch after both sides showed their strong suits at different stages last week. Declan Browne nearly beat Clare on his own and still had time to miss the penalty that probably would have made sure. Then in the second half Clare's hardy resilience came to the fore and they nearly won. The original calculation still holds though. Tipp's attack with Browne, Brendan Cummins and the evergreen Peter Lambert has the penetration to put up a better score than Clare's more laboured unit. After that it's a matter of improved concentration but Tipp look more likely to repeat the scoring than the lapses.

TIPPERARY: P Ryan; N Sheehan, N Kelly, D Byrne; B Hahessy, N Fitzgerald, W Morrissey; K Mulryan, S Maher; D O'Brien, B Cummins, L England; P Lambert, P Cahill, D Browne.
