London Irish player coach Mike Catt insists Friday night's stunning win over Leinster will mean nothing if the Exiles fail to beat the Scarlets this weekend.
Catt saw his side defeat the reigning Heineken Cup holders on their own ground six days ago but the former England and Lions star claims his side have not been getting carried away with the magnitude of that achievement.
Instead, once they arrived back home on Saturday morning, Irish put that stunning victory to the back of their minds and immediately began focussing on their impending clash with the 2007 semi-finalists at the Madejski Stadium.
"For us, it's just about focusing on the next game. If we don't win on Saturday, Friday night's just out of the window," said Catt, who was a Heineken Cup winner with Bath back in 1998.
"As a group of players, that's the mentality. We haven't won anything.
"Our goal for the season is to win the next game. That's all our focus is. We know that if we do that, we give ourselves a very, very good chance of being there or thereabouts in the competitions we're in."
Few critics were predicting that the Exiles would run out 12-9 winners over Brian O'Driscoll and co on the opening night of European action but the impressive nature of that victory has not stopped Catt demanding even more from his players and team-mates.
Having won the 2003 World Cup with his country, Catt knows exactly what it takes to be successful at the highest level of the game and he is determined that his current side will learn to develop a similar consistency.
"We have matured massively over the last three years," added the 37-year-old.
"It's now about putting games together and being consistent throughout the season. It's vital that we keep developing as a team. That's all we're trying to do.
"It's vital that we get our shop in order. We did pretty well in the lineouts against Leinster, but Leinster did pretty well in the scrum against us. So there are a few things that we need to tweak and make sure that we get right so that we don't get put on the back foot and are forced to kick a lot of the time.
"It's another massive challenge for us at the weekend. We're excited about it. It's a first time in the Heineken Cup since 2008 and if we can start off with two positive results, that'll stand us in good stead for the future."
