The pain of London Irish's back-to-back European defeats to Premiership rivals Gloucester Rugby is still raw and outside half Ian Humphreys accepts there have to be rapid improvements for them to get on the road to recovery.
And Humphreys - who missed the 47-3 rout at Kingsholm when the Exiles leaked a stream of tries - admits the Exiles have under-achieved so far this season.
They trail Gloucester by seven points in Pool 1 and face French tests against Bordeaux-Begles and Mont de Marsan when the tournament resumes in the New Year.
"I think it is fair enough to say that we have under-achieved so far if you look at our squad," said Humphreys, who has scored 245 points in Europe for Leicester Tigers, Ulster Rugby and now the Exiles.
"But there is enough time between now and the end of the season to go on a good run. The Amlin Challenge Cup is probably gone now, but there are other opportunities to do well.
"On paper our strongest team is pretty strong and there have been glimpses of what we can do in games.
"Now we have to start doing it for 80 minutes and not just for 20-minute or 40-minute spells here and there.
"There isn't anything wrong with the system we are playing, it is down to individual errors, mistakes in defence or in attack, and they are proving costly. We have to prevent them from happening.
"We have got to start putting in some performances at the Madejski for our fans. It has been frustrating for those who turn out to watch us and we are determined to give them something to cheer.
"We have got about six or seven more home games to go and that is where we need to start delivering."
