Welcome to our coverage of Leinster's Champions Cup clash with Bath at the Aviva Stadium (kick-off 5.30pm) and Munster's Champions Cup clash away to Castres (also 5.30pm). This evening both provinces have the opportunity to put themselves on the brink of a place in the quarter-finals of the Heineken Cup. Tonight the defending champions must get to grips with Sam Underhill and the tempestuous Dublin weather as they bid to put further daylight between themselves and English Premiership opposition in Pool One. Munster meanwhile comfortably put Castres away last weekend, winning 30-5 in a fixture memorable for the scoreline and not much else. Brutal retribution could be on the way in the home of the Top14 champions - but victory would put Johann van Graan's side firmly in the driving seat in Pool Two.
