Exeter Chiefs head coach Rob Baxter expects his side to face 'a real battle' when they travel to South Wales for Sunday's Challenge Cup return against Newport-Gwent Dragons.
The Chiefs beat Newport 18-6 at Sandy Park last week to go top of Pool 4.
But Baxter expects the return fixture at Rodney Parade to be 'tough'.
"We've got to get ourselves ready for a real battle up there. They're a very side and Rodney Parade is a tough place to go," Baxter told BBC Radio Devon.
"It's a fantastic place to play rugby, but it's a tough place to go and win.
"We've got to be ready to crank things up physically and fire ourselves into a very tough game. But we've got it in us."
The Dragons will be seeking revenge for Sunday's defeat, visiting coach Darren Edwards having admitted that it is vital that they beat Exeter.
The Chiefs lead the group by a point from the Dragons, who are level with Perpignan on points.
A win for Exeter could see them go as much as six points clear of the Welsh side.
The Chiefs have two games to go, including a trip to Italy to face bottom side Cavalieri Prato, who have yet to gain a point in the competition.
