Saturday's vital home win against Gillingham was followed by a 2-0 success at Lincoln on Tuesday night, a performance that Sampson called 'very professional' when speaking after the game.
'All the players did well and I thought we were the better side', he told the official club website.
Having guided the Cobblers to one of the most famous results in their history in the League Cup earlier this season, Sampson has no intention of taking the upcoming FA Cup any less seriously.
'We want to keep this run going at Forest Green on Saturday'.
Forest Green are currently struggling near the foot of the Conference but gained a morale-boosting home win over York City at the weekend.
