Nathan Collins admits he has been left with a selection headache.
His Poachers side will begin their UCL Premier campaign this weekend.
But the Boston Town manager still has to decide on the team which will kick off at AFC Kempston Rovers.
“The lads are very aware that there is competition for places here at the moment,” he said.
“Unfortunately, I’ll have to leave three or four out of the squad on Saturday - but that’s my headache.
“All the lads are extremely focused and I’m upbeat after a good pre-season.”
The Poachers ended their warm-up matches on Saturday with a 1-1 draw at Barton Town.
Alex Beck (pictured) scored for Town and also saw two good efforts saved before the hosts levelled late on.
But despite the scoreline, Collins was left with a good impression.
He added: “It was the most one-sided draw I’ve been involved in.
“Alex scored a very good goal and also saw two point-blank efforts well saved by their keeper.
“We played well and outpassed them for most of the match.”
But despite the pleasing football, Collins refuses to get carried away.
“It was very encouraging,” he added.
“But at the end of the day we know pre-season doesn’t always carry on to league matches.
“Teams could have a good pre-season and then lose their first five matches, and we don’t want to let that happen to us this year.”
