There was a frisson of excitement around Franklin’s Gardens on Friday night as Saints’ swagger returned.
It hadn’t been seen since mid-March, but Jim Mallinder’s men finally rediscovered their best form at the expense of Harlequins.
There was tempo to their play, aggression and a dogged determination in defence that left Quins, with their quartet of England stars, reeling.
Danny Care, Mike Brown, who went off injured at half-time, Joe Marler and Chris Robshaw were powerless to prevent their side slipping to an 18-10 defeat.
Instead it was Saints’ squad which came to the fore, with none of the men who represented England in the Six Nations in the starting line-up.
It was reminiscent of the times during that tournament when players came from nowhere, stepped up to the plate and drove the club forward.
It gave the England players another reminder of the talent that is lying in wait if they fail to perform, and that can only be a good thing ahead of a huge few weeks.
Saints now have an Amlin Challenge Cup final to look forward to, added to an Aviva Premiership play-off semi-final.
And the European progression is undoubtedly a good thing as it eases a little pressure in the pursuit of silverware.
Should Saints win the Amlin, it could prove to be the catalyst for Premiership success.
Why? Because the club go into the game at Cardiff on May 23 having lost their past four finals.
If they were to win the European encounter, it could inject the belief needed to secure the league title, presuming Saints make it through the semi-final tie.
With the kind of form they showed at the Gardens on Friday night, Mallinder’s men are capable of achieving their aims.
They now need to ensure they now remain on an upward curve going into a month that could become the best in the club’s history.
