Ospreys come into the Round 3 encounter at Swansea.com Stadium yet to taste victory in Pool A – they were beaten 21-13 by Sale Sharks in Round 1.

Meanwhile, Racing return to the fray having thrashed Northampton Saints 45-14 on the opening night, and Booth has insisted that the three-time finalists are going all out to lift the trophy this season.

“Racing are on record of saying how seriously they are taking this competition and they are not afraid to shy away from that,” he told Ospreys’ website.

“Traditionally, sometimes the teams that travel from France are not always their strongest, but this is going to be as good as they have got.

“From last week’s selection they are all fit and we are expecting the best team possible.

“We have got what we have got, with a lot of young players and this is a learning and challenging opportunity for our youngsters. We will be better for it, win, lose or draw.”

One of those youngsters is back row forward Will Hickey, who is set to make his Ospreys debut from the bench against Racing.

“I’m very excited to make my debut on Saturday,” he said. “I’ve been working towards it for quite a while now so it’s very exciting to pull on that jersey to represent the group and the region."

“It’s been a great experience being at the Ospreys. They're a good bunch, the senior players are really humble and don’t hesitate to integrate you into the group and I get on with a lot of the younger boys too.

“I’m hoping to get as many opportunities as I can to play the rest of the season whether it be for the first team or the A team and make the most of everything that comes my way.

“Hopefully I’ll get a good runout on Saturday and rack up as many games as I can before the season closes.”

Ospreys head coach Toby Booth says his side are readying themselves for the strongest side Racing 92 have to offer when they host the TOP 14 outfit in the Heineken Champions Cup tomorrow.
