Jim Mallinder called for a season’s best performance from Saints at Saracens on Sunday - and that was exactly what he got.
In fact, the director of rugby witnessed perhaps the most impressive performance of his six-year Northampton tenure.
Saints did not just beat Saracens.
They beat them up, physically and mentally.
Led by human wrecking balls Dylan Hartley, and in particular Samu Manoa, Mallinder’s men marched into a 17-0 lead.
And they didn’t look back.
They put Saracens under immense pressure during a scintillating first 40 minutes and the cracks appeared in a side who have now lost four successive semi-finals in all competitions.
Saints, of course, were bidding to avoid a fourth successive Premiership play-off semi-final defeat, and they not only banished the hoodoo, they smashed it to pieces.
Manoa was magnificent.
Hartley was hungry. The Saints players hunted down their opponents in packs, then mauled them.
There were two things no Allianz Park spectator would have wished they were: A Saracens player or a tackle bag.
Because right from the warm-up, Saints showed their intent. They hammered all before them and refused to be beaten, even when they went down to 14 men.
During that period, after Jamie Elliott saw yellow for a late tackle, Saracens scored once through Duncan Taylor.
Had they scored twice, they would have been back within a score of Saints.
But the away side, with a siege mentality, held out.
GJ van Velze, who has scored four big tries this season - at Ulster, Exeter and Saracens and at home to London Irish - finished the job.
Saints had a famous victory - one their fans were due after three years of agony in the league and the Heineken Cup.
Of course, they may not beat local rivals Leicester Tigers, who have won the past seven meetings between the sides, at Twickenham on May 25.
But when they finished fourth in the regular-season standings fourth, all they could ask for was a shot at them.
They’ve got that.
Now, if Mallinder somehow gets another season’s best out of this defiant bunch, the trophy might, just might, be heading to Northampton.
