Northampton welcome back several England internationals for their hosting of Wasps at Franklin's Gardens this Saturday.
Saints lifted the LV= Cup last Sunday, but Mallinder insists that that competition is firmly behind them as they look forward to another top-four Guinness Premiership clash.
"The LV= Cup was a good competition for us but our attention is now firmly on the Guinness Premiership," he said this week.
"We've got a hard few weeks in front of us, starting on Saturday.
"Wasps are a tough side. They will have a few players back from international duty and from injury and they know how to win games at this stage of the season, when they always seem to be there or thereabouts in the push for the play-offs.
"It is a big game, which we are having every week now. But this is where you want to be as a player or as a coach. We've won a competition and are competing in another two, but success only comes one game at a time."
Meanwhile, Wasps Rugby Director Tony Hanks has named a strong team for the trip to the Gardens.
Tom Payne and Joe Worsley are back from international duty while scrum-half Joe Simpson, lock George Skivington and flanker Tom Rees. Rees, who is making his first appearance of the season following a shoulder injury, also captains the side.
"We are delighted to welcome Tom Rees and Joe Simpson back to the game," Hanks said.
"Both players have shown huge resolve and focus to work through their rehab programmes which, especially for Tom, have been lengthy. Although they have not been seen on the pitch over the past few months, their contribution to the team has been huge behind the scenes and everyone is pleased to welcome them back to action.
"To have these guys back in the mix, alongside George Skivington and our England pair of Payne and Worsley, there has been a real lift at the Club this week. The performance at Sale was not good enough by our own standards and we are very focused on this week's game and a strong performance against Northampton that reflects our own high expectations."
