  1. Confident Edmund can win in all conditions

    Confidence is a big thing. He's got some big wins, beating someone like Kevin Anderson in the first round really sets you up for a good run, and then he beat Basilashvili in really tough conditions.

    I think he's confident he can win in all situations and doesn't have to play his A level game all the time. He's more experienced and won't panic if his game slips for a game or two. He has a plan B now.

  2. Kyle Edmund and Andreas Seppi have just been announced to the crowd on the Hisense Arena.

    I wonder how Edmund is feeling before this one. He lost his last Grand Slam fourth round match to Novak Djokovic at the 2014 US Open.

    He's looked a different player in this tournament though.

    Game, set and match

    And the winner of that Nadal-Schwartzman match will play Marin Cilic in the last eight.

    The Croat, winner of the US Open in 2014, has just knocked out Pablo Carreno Busta 6-7 (2-7) 6-3 7-6 (9-7) 7-6 (7-3).

  4. Game and first set

    Nadal 6-3 Schwartzman

    Over on Rod Laver Arena Rafael Nadal has taken the first set against Diego Schwartzman.

    If Nadal wins today, then he will keep his title as the world's best when the new rankings are released on 29 January - a loss here and a Federer title victory would see him drop a place.

    Nadal hasn't dropped a set yet in Melbourne, and he has looked imperious during his three victories so far.

    His opponent, Schwartzman, has never reached the quarter-finals in Melbourne. His best performance at a Slam was reaching the last eight at last year's US Open.

    Nadal leads their head-to-head meetings 3-0, winning all of their encounters in straight-sets.

    Gulp. Plenty to do from a set down then.

  5. Who wins?

    Andreas Seppi doesn't have a blockbuster shot to hurt you with but Kyle Edmund does. If Edmund plays his best game, he wins.

  6. Edmund v Seppi

    The rankings suggest 23-year-old Edmund should win this one but of course it is never that simple.

    They are players at the opposite ends of their career and 33-year-old Seppi is a former top-20 player, having reached 18 in the rankings in 2013.

    That said, he too is aiming for a first Grand Slam quarter-final. One player will be breaking new ground in a few hours time.

  7. Forehand v backhand?

    It's a pleasant 25C this afternoon and the forecast rain has yet to turn up, although that could provide an interruption later should the roof be required.

    Edmund will have had to cut short his preparation as the preceding doubles match ended prematurely with a retirement. As he said after his gruelling five-set win on Friday, however, he's had "two sleeps" to get ready for this one.

    It could well come down to a battle between the Edmund forehand and the Seppi backhand, the two go-to shots on display this afternoon.

  8. The official word is that Kyle Edmund and Andreas Seppi will make their way onto court at 5:15 GMT.

    That's a little earlier than we were expecting due to a retirement on Hisense Arena in the doubles match which preceded this last 16 tie.

  9. Day seven in Melbourne

    World number one and last year's finalist Rafa Nadal is in action on the Rod Laver Arena as we speak against Argentina's Diego Schwartzman. They're midway through the first set.

    Croatian sixth seed Marin Cilic is also currently in action against Spain's Pablo Carreno Busta. He is leading by two sets to one.

    Nadal and Schwartzman are followed by home boy Nick Kyrgios, who plays world number three Grigor Dimitrov in a repeat of the Brisbane semi-final earlier this month.

    Ukranian fourth seed Elina Svitolina then rounds off the evening session with her match against Czech Denisa Allertova.

    Caroline Wozniacki has already cruised into the quarter-finals with a 63-minute win over Magdalena Rybarikova.

  10. Edmund v Seppi

    Hello there! Welcome along to our coverage of day seven of the Australian Open.

    Shortly British number two Kyle Edmund will begin his last 16 match, aiming to reach the quarter-finals of a Grand Slam for the first time in his career.

    If he does so he will be the first British man other than Andy Murray in the last eight of a slam since Tim Henman in 2004 and the first reach the quarters in Melbourne other than Murray since John Lloyd in 1985·

    Standing in Edmund's way is Italian world number 76 Andreas Seppi.

    This should be straight forward... right?
