Holbeach United manager Darren Jarvis accepts that physiotherapist Carol Holland has earned a chance to work at a higher level.
She rejoined St Neots Town last week with Jarvis saying it was “a real shame” to see her leave Carter’s Park.
Jarvis added: “I gave her a first position in football a few years ago so she’s a good friend as well as being a great physio.
“She deserves to be at a higher level with all of her qualifications.
“It’s a huge loss for us but it was too much of a good opportunity for her to turn down professionally and financially.
“We will be working hard to find a replacement for next season.”
Meanwhile, Jarvis remains hopeful of persuading last term’s top scorer Jamie Clarke to sign again with the Tigers.
He admitted: “We want him to stay at the club but I accept that the travelling distance from his home and work commitments may also influence his decision.”
The Tigers have already agreed deals to sign keeper Ricky Drury, central defenders Jonny Clay and Chris Ward plus midfielder Andy Law.
Jarvis said: “We are pleased because they fit the profile which we are looking to achieve with our additions to the squad.
“We want to find the best players locally before casting our net further afield.
“Jonny and Andy played for me at Peterborough Northern Star so I know all about them.
“From a very early stage when myself and Tom Roberts took charge here, we were very confident that Jonny would want to play for us again.
“He was an influential leader for us while Andy is a valuable addition as a versatile player with great quality on the ball.
“Chris is a former England schoolboy international who lives locally and wants to progress his career after playing 20 times for King’s Lynn Town last season.
“Ricky has shown great desire to come here but Nick Conroy has been invited back for pre-season so it’s up to him whether he wants to challenge for the number one jersey.
“We have got quite a few irons in the fire and the squad is shaping up really well with more to come in.”
Jarvis also confirmed that Clay has fully recovered from a hernia injury which kept him out of action for the second half of last season.
