**Guinness Pro14 Conference B leaders Edinburgh are looking to maintain their winning start to 2020 as they welcome mid-table Cardiff Blues to BT Murrayfield on Friday night.** Last Friday’s 41-14 win over Connacht was Edinburgh’s sixth successive home win in the competition and kept them three points clear of Munster at the summit. The next hurdle for Richard Cockerill’s side to overcome takes the form of a Blues side who came from 19-7 down to beat Bennetton Rugby 34-24 last weekend. That was the Welsh side’s first victory since Boxing Day and moved them just one point behind fourth-placed Connacht. Edinburgh won a hard-fought reverse fixture 19-11 at Cardiff Arms Park in Round 2 and are looking to complete a double which would further cement their place at the top of the table. **Kick-off:** 7.35pm **How to watch:** Live on Premier Sports, DAZN, pro14.tv **Players to look out for:** Duhan van der Merwe (Edinburgh), Jason Harries (Cardiff Blues) No matter what the level, clubs are always wary of former players returning to haunt them – often with good reason. Jason Harries’ return to BT Murrayfield last season proved a perfect example of why, as the former Edinburgh winger came off the bench to score twice and set up the other in a famous 19-17 win for Cardiff Blues. He will be hoping for a similar impact this time around but faces one of the Guinness Pro14’s in-form wingers in Duhan van der Merwe. The 24-year-old South African has scored in each of his last five matches, a key factor behind Edinburgh’s recent good run. **Key stat:** No Conference B team have scored more tries than Edinburgh (43) this season, while only bottom club Isuzu Southern Kings have crossed for fewer scores than Cardiff Blues (26). **Edinburgh**: Damien Hoyland, Eroni Sau, James Johnstone, George Taylor, Duhan van der Merwe, Simon Hickey, Charlie Shiel, Jamie Bhatti, Mike Willemse, Simon Berghan, Lewis Carmichael, Grant Gilchrist, Nick Haining, Luke Crosbie, Villaime Mata **Replacements**: Cameron Fenton, Pierre Schoeman, Pietro Ceccarelli, Sam Thomson, John Barclay, Henry Pyrgos, Jaco van der Walt, Chris Dean **Cardiff Blues:** Hallam Amos; Jason Harries, Garyn Smith, Ben Thomas, Aled Summerhill; Jason Tovey, Lloyd Williams (capt.); Brad Thyer, Kristian Dacey, Dmitri Arhip, Seb Davies, Rory Thornton, Shane Lewis-Hughes, Olly Robinson, Josh Turnbull **Replacements**: Kirby Myhill, Corey Domachowski, Keiron Assiratti, Ben Murphy, Will Boyde, Lewis Jones, Max Llewellyn, Dan Fish
