The newly revamped Guinness Pro 14 season will kick off this weekend, with the addition of two new South Africans teams to the previous 12-team setup.

For the Irish provinces, there have been varying degrees of change on and off the pitch.

New (and in the case of JJ Hanrahan at Munster) familiar faces will abound for all four sides with Leinster's new duo James Lowe and Scott Fardy, Connacht signing Jarrad Butler, Ulster acquisition Jean Deysel among those to look out for during the 2017-18.
