**Edinburgh need a win when the Scarlets visit on Saturday or risk being left behind in the chase for Heineken Champions Cup rugby.** \n\nRichard Cockerill’s side have two games in hand over the third-placed Scarlets but are 11 points adrift ahead of the Murrayfield clash. \n\nWith Cardiff Blues – who are seven points ahead of Edinburgh and at home to Munster on Friday night – also in the mix, closing the gap is a matter of urgency for the men from the Scottish capital. \n\nEdinburgh were beaten at home by Conference B leaders Munster last time out, while the Scarlets were comfortable victors over basement boys Benetton. \n\n**The breakdown**\n\nThis weekend’s hosts will take confidence from their recent record against the Scarlets, having won the previous six meetings between the sides.
