Boston United manager Dennis Greene has said it would be “crazy” to make drastic changes for next season.
United suffered a 3-2 aggregate loss to North Ferriby United in the National League North play-off semi-final.
But Greene, who has a year left on his contract, told BBC Radio Lincolnshire: “The group is good enough. We just need to add one or two more to it.
“Most of this group have been with us for two years and we have had two play-off campaigns.”
Greene, who first took over as Pilgrims boss in March 2013, added: “It would be crazy to get rid of them all. We just need to add one or two more and maybe have a better season with regard injuries.
“The team that finished the season in the last seven or eight games that was pretty much unchanged could challenge for the top slot; we just never quite had the luck with injuries this season.”
Boston led 2-0 after the home first leg, but a controversial penalty given when Carl Piergianni tangled with Tom Denton in Sunday’s return fixture saw them concede an early goal, and they went on to lose 3-0.
“We are devastated,” Greene said. “The penalty is not a penalty in a month of Sundays. That gives them a kickstart and then the belief.
“The second goal I thought was a foul on the keeper and the third goal Nat Brown is down with a head injury and they score.
“The man in the middle had a part to play in all three goals. Not one decision went our way so it was difficult to take. On the whole they deserved their victory but it was handed to them on plate by the officiating.
“We never got going. Ferriby got in our faces and they have to take credit. They took their chances and we didn’t. We never managed to find the final ball.”
