The new era kicked off with Holbeach United’s biggest away defeat of the season.
But Tigers manager Darren Jarvis remains confident of halting a poor run by sending Newport Pagnell Town to a seventh successive league loss at Carter’s Park on Saturday.
He said: “Managers have a habit of making excuses but I don’t like doing that.
“Any team which goes to Thurnby Nirvana will get a tough game as they are an outstanding side.
“We went over there on Tuesday night with a bit of a ‘scratch side’ out as we are missing five players.
“At full strength I would always back the team to get a good result.
“I thought 3-0 was a little bit generous for them.
“We thought we equalised with Aiden Kirby’s free-kick but it was indirect and a few seconds later it was 2-0.
“Overall I was really happy with the contribution of the boys who are helping the club and I thought Jack Smith in particular was outstanding.”
Skipper Matt Melbourne gave Nirvana the lead on the half-hour mark.
Lynas King doubled the lead four minutes into the second half.
Top scorer Liam Canavan wrapped up the win with his 27th goal of the season eight minutes past the hour mark.
Holbeach are set to bring back Andrew Tidswell and Stacy Cartwright on Saturday while Danny Steadman may also return.
Niall Delahoy and Craig Parker should be available again at home to Sleaford Town next Wednesday.
Looking ahead to his home debut in charge, Jarvis added: “Newport Pagnell have got a loyal set of players with a great team spirit.
“You know it will be a hard battle against them because they work for each other.
“Dominic Lawless has always scored goals so we are expecting a tough game.
“But if we get the same commitment and work-rate which the players showed at Thurnby on Tuesday then I would expect us to win this match.
“I’m really looking forward to it.”
