**Defending champions Leinster will welcome Munster for a box office inter-provincial derby at the Aviva Stadium when the Guinness PRO14 resumes later this month.** The countdown to the much-anticipated restart continues apace and we start today’s Media Watch with [a word of caution from Leinster head coach Leo Cullen](http://www.rte.ie/sport/rugby/2020/0805/1157539-world-cup-winners-wont-guarantee-munster-success/) to Munster. Munster have four new signings in their ranks in the shape of World Cup-winning Springboks RG Snyman and Damien de Allende, bolstering Johann van Graan’s squad significantly. But Cullen has warned Leinster’s Irish rivals that bringing in World Cup winners is no guarantee of success, even if it’s good to see such high profile talent coming to the Guinness PRO14. Staying with Leinster, the Irish province have received a boost after Cullen revealed second row star James Ryan is ['flying' through recovery from his shoulder surgery](http://www.the42.ie/james-lowe-farrell-ireland-5169197-Aug2020/). Ryan is already running and lifting weights in the gym, with Cullen hopeful he could be fit for the club’s Champions Cup quarter-final clash with Saracens in September. The news will be music to the ears of Ireland head coach Andy Farrell, who has also challenged James Lowe to show his best form for Leinster to [press home his international claims](http://www.the42.ie/james-ryan-leo-cullen-leinster-5168727-Aug2020/). New Zealand native Lowe qualifies for Ireland in November after three years of residency and with the new ‘Eight Nations’ competition upcoming, he is expected to be in the mix for Farrell’s men. “He’s been great, he’s been a great tonic for Irish rugby really and he’s played some outstanding rugby over the years,” said Ireland boss Farrell when asked about Lowe’s ability.
