It's Premiership semi-final week, so to kick things off we have a special episode with the directors of rugby from the four clubs competing for a spot at Twickenham this weekend. Mark McCall, Johann van Graan, Phil Dowson and Alex Sanderson are all together to chat to Chris about the challenges of a season that was delayed by the World Cup and put on hold during the Six Nations. Does a 10-team league work? And are we any closer to achieving promotion and relegation? They also discuss big name players leaving for France and whether the RFU should relax its eligibility rules for overseas players. And with four of the best fly-halves around on show this weekend, each DOR explains why their 10 is the best.
