Rob Baxter has underlined the need for his Exeter team to hit the ground running when they resume Aviva Premiership business against struggling Worcester on Saturday.
The Chiefs have enjoyed notable success in the past few weeks, crushing Gloucester at Kingsholm, then destroying Heineken Cup opponents Cardiff Blues before picking up a losing bonus point away from home against Glasgow.
"We have to flick that mental switch now, because we know it's going to be a very important game for Worcester, but it's also a very important game for us," Exeter head coach Baxter said.
"Nothing else but 100 per cent concentration and focus will do in the Premiership. We will be looking to ram that home to the players."
Worcester have lost their first five Premiership games and are seven points adrift at the basement, but Baxter added: "Everyone is very aware that the challenges of playing a team that is fighting away are huge.
"That is why I am so determined to make sure the most important thing we do is not get too carried away or focused on what happened in the Heineken Cup. As far as I am concerned, that's done now.
"Teams that claim to be ambitious and want to be involved in big games at the end of the season are good at this stage of the season.
"Coming out of the Heineken Cup they are tough and they make sure they get the results they need to keep the season alive."
Elsewhere on Saturday, Premiership leaders Saracens will target a sixth successive league win when they visit Northampton, while Harlequins host Sale, but the action begins on Friday night with a west country derby between Bath and Gloucester at the Recreation Ground.
After two weeks of European action, when Bath claimed victories over Bordeaux-Begles and Newport Gwent Dragons, attention now turns to hosting one of their fiercest rivals.
"Gloucester will be up for it. Maybe they haven't started the season as well as they would have liked, but in a game like this they will raise their game and we have to be ready for them," Bath's England international wing Matt Banahan said.
"Form goes out the window when you play a local derby on a Friday night under the lights, so we are going to have to be at the top of our game.
"We are happy with the way we kept our momentum going during the European break, picking up two important wins and putting ourselves in control of our group.
"And now we want to keep going in the Premiership. It's an exciting time for the club. There is a lot of competition for places and everyone is raising their game."
Gloucester have won on three of their last five league visits to Bath, but their Premiership form this season has proved patchy.
