Saracens will look to continue their Champions Cup domination when they host Ospreys at Allianz Park on Saturday evening.

Mark McCall’s men will be in high spirits after their incredible 57-13 dismantling of Northampton Saints in the first Pool 2 clash last weekend.

Schalk Brits and Juan Figallo are set to replace Jamie George and Vincent Koch as McCall shuffles his pack, while Duncan Taylor is out as a precaution after sustaining a head injury last weekend.

The mood at Saracens will be boosted by the news that young star Alex Lozowski has signed a new contract, keeping him at the club until 2020.

Ahead of the clash with the Welsh side, Lozowski said: “It’s a competition that we know is really tough. So, I suppose now it’s about backing it up this weekend against Ospreys.

“I think everyone’s just excited about getting back at home, in front of our home fans, and hopefully putting ourselves in a really strong position in the group.”

Flanker Calum Clark also warned that Saracens must focus and not get complacent, despite their impressive form this season.

He said: “They are an unbelievable group of players and they will be right at it this week coming to us. So, we have to go up a step again.

“We can’t expect that what we did last week was anywhere near good enough to win again.
