Following all the hype, last weekend’s return to European rugby did not disappoint in the slightest. Last minute-penalties, red cards all over the shop, it was the weekend that kept on giving, and with the return fixtures following right behind, there are bound to be scores to be settled. The same teams playing, but at different stadiums, and plenty more on the line, here are five big questions heading into round four this weekend. Can Munster give Sarries the boot? What perfect revenge this could be for Munster this weekend, as they have the chance to all but end the Champions Cup reign for perennial nemeses Saracens. The trophy holders kept their hopes alive with a losing bonus point in last weekend’s 10-3 defeat at Thomond Park. But if Racing continue their imperious European form, we could be saying goodbye to Owen Farrell and co. before we’ve finished our advent calendars.
