Here's some footage from yesterday's practice session.
Edit: Starting on Monday (as David and the others will get the day off tomorrow; source) there'll be two training sessions per day while the German team starts training on site tomorrow. The "roadmap" relased by the AAT says that the press conferences will take place on Monday, which would be unusal as normally, it's Tuesday - we'll see. But in any case the draw ceremony plus press conferences is scheduled for Thursday, at 11am local.
In other words, it's a busy week that lies ahead of David - and of us.
Apart from that, I already mentioned it in the comments, there's a new TV interview that David did for Argentine ESPN+ and that will be aired tomorrow. Ahead of the broadcast, ESPN have relased a 7-minute preview on their website. This clip includes David's replies to questions about his prospects, injuries, becoming a father - and about the Davis Cup, where without actually naming any names David makes it very clear what he thinks about the latest developments concerning the team.
I've put the clip itself and my summary/transcript of it in a backdated post that you'll find here.
