Delaney’s men will travel to the south of France a week on Saturday after the game was given the go ahead despite the ongoing Covid-19 pandemic.
“It’s a big two-week build-up. The boys have regenerated well. They are full of energy and looking forward to next week,” said Scarlets head coach Delaney.
“It is very different (playing a quarter-final in September), but I guess there is nothing normal about this year!
“It is going to be warm out there so it could be a good chance to move the ball around and certainly play the way we want to play.
“Toulon are a quality team full of very good players and they know how to win, particularly at home. It is going to be an enormous challenge.
“We had a big challenge from them last year when we went down there but just didn’t quite get home.
“We are feeling good about how we are preparing and are excited about getting down there and putting a stamp on the game.”
TOP14 giants Toulon are one of the biggest and best sides in European rugby and always boast a star-studded squad.
They have won the Heineken Champions Cup on three occasions.
The Scarlets have faced them plenty of times in recent years in European competition.
Their last meeting came in January with Toulon 27-15 winners at a wet Parc y Scarlets where the French side’s power game told.
Prior to that, the Scarlets were only beaten by a point at the Stade Mayol in November despite being reduced to 14 men.
“Every time you go to France and perform it builds some confidence in you,” said Delaney.
“We have also taken confidence from the two derby games we have just played and that has given us areas to look at and what still needs a bit of tinkering with.
“For the most part, we have a full deck of players to pick from and are all putting their hands up.
“Pretty much everyone is back in training with very few guys in the long-term injured group. We have had a couple of notable guys back in the last two to three weeks which has been great.
“We are building nicely and the key thing is we will put the best team out to represent the region and all the people from out west.
“We have a very competitive squad. We know the hardest thing we have to do as coaches is pick the team. Often we are having to leave out really good people and that is the challenge.
“They are all putting their hands up. All we can ask is they give us the best reason to select them. It is a massive eight days ahead.
“We will keep the energy high and keep guys focused moving forward.”
