Steve Housham believes Jan Budtz's arrival has given him a welcome selection dilemma and finally ended Gainsborough's goalkeeping concerns.
The Blues swooped for the ex-Hartlepool goalkeeper last week as part of a triple swoop which included moves for Sam Mulready and Danny Hone.
After using six goalkeepers last season following a horrendous run of injuries and unavailability, Trinity suffered another blow when they lost Phil Barnes to Alfreton in the summer.
But Housham moved to bring Budtz to the club and hopes he and Jason White will put an end to Trinity's concerns over the number one spot.
"It looks like I have a tough choice now," he said.
"Jan's come in but his arrival was absolutely vital.
"We need two keepers this year because to go through six last year must have broken some kind of record.
"It nearly cost us in November of last season because we only claimed one point then.
"To bring somebody in of Jan's quality is brilliant for the club and good for Jason.
"They will push each other and as a manager there is nothing better than having competition for places."
Hone's arrival will also give Housham welcome strength in depth at the back.
He will challenge Greg Young and Luke Waterfall for the centre-back positions after the former Lincoln City defender impressed on trial.
"Danny did very well for us," he said.
"He trained brilliantly with us and it was certainly an area we needed to strengthen.
"We only had Youngy and Luke Waterfall, so we were a bit short in that area.
"But Danny has come in. He's versatile, he can play at right-back or centre-back and I have been delighted with what he has done in pre-season."
Hone will be hoping his move to Trinity can help launch him back to the Football League where he made his debut with Lincoln.
Former Trinity defender Andrew Boyce last week said that dropping down the leagues was not necessarily the end of a player's career.
And Housham says Trinity could be the ladder that takes Hone back to greater heights.
"Danny has not come for mega money and I am delighted he is here," he said.
"And You never know, it could be a stepping stone for him for him to move back up the leagues again.
"Sometimes you need to take a step down before going back up again and that's not just with Danny, it's the rest of the players.
"Andrew Boyce got a great move and he deserves everything he gets.
"He's a good player and he will be a good acquisition for them.
"It shows that anybody can do the same and while my job is to get results, I also want to develop players."
