But after only three games in charge, Davies has guided the Scarlets to the top of the table and reckons they can continue their impressive start to the season at Murrayfield.
Davies said: "It was important to have a good start to the season - this has underpinned the work we did in pre-season.
"But we realise that Edinburgh is a massive game for us and if we don't keep our focus, then all the work of last week will be wasted.
"We don't have a very good record against Edinburgh and an awful one in Scotland. We've spoken about that and we're trying to approach the game differently to what we have done in the past."
The Scarlets are without the injured Simon Easterby, Simon Maling, Deacon Manu and Mahonri Schwalger but 21-year-old hooker Ken Owens gets a chance to impress.
Owens said: "It's nice to get the chance to try to prove myself against good opposition.
"There's a feel good factor at Stradey Park and it's a lot easier to step into a winning team than a losing one. Hopefully I can bring something extra to the pack."
