Pat Rayment wants Spalding United to find top form in their final four friendlies before the big kick-off.
The Tulips boss is demanding high standards ahead of the Evo-Stik League First Division South campaign.
They face Holbeach United on Saturday and another home game against St Ives Town next weekend, along with midweek trips to Boston Town and Peterborough Northern Star.
The scheduled game at Farsley Celtic on August 8 has been called off in favour of ‘a bonding session’.
Rayment said: “We know the Holbeach game is going to be competitive – that’s why we arranged it because this should be a good pre-season fixture.
“We know all the faces in their team and we are well aware of what every single player can do.
“They have got some very good players and I’ve gone on record in the past to say how good I think Jamie Stevens is.
“We have assembled a new team but we haven’t kept a clean sheet yet.
“We conceded two very poor goals on Friday at home to Stamford after two poor goals at Wisbech Town and another at Oakham United.
“I know it’s only pre-season but we need to get into the right habits now.
“Of all the players we’ve brought into the club during the summer, the front line should be the strongest part.
“It might take time for them to gel but they are playing in the right positions and we expect them to score goals.
“If you look at the backgrounds of Josh Moreman and Michael Frew – along with Tom Waumsley who was our top scorer last season – and ask if they are going to get goals for us then the answer must be categorically ‘yes’.
“They have got to start hitting the ground running and finding form – starting on Saturday.
“Over the next four games I want to see us get out of the traps so we are ready for the first league match at Romulus on August 15.”
