Gillingham captain Andy Frampton praised the character and unity in his side after knocking League One Bournemouth of the FA Cup.
The Gills made four changes for the Cherries' visit, but earned an impressive 3-2 victory.
Frampton told BBC Radio Kent: "It shows we've got great competition within the squad and a great unity.
"The gaffer has put a squad together. He's just shown that we can change our side and still turn out a performance."
With Danny Jackman, Barry Fuller and Danny Spiller injured and Frank Nouble and Jo Kuffour ineligible, the first round replay provided an opportunity for other members to prove their point to manager Andy Hessenthaler.
Stefan Payne particularly impressed, firing a stunning winner midway through the second half to earn Gillingham a trip to Leyton Orient in the second round.
Frampton said that having won five of their last eight games, the Gills are starting to gel at just the right time.
"Character is a big part of football and this season I feel we've got it in the changing room," he said.
"The lads showed good character to hold on at the weekend. It's certainly looking very bright.
"It's always been there but we've put a lot of players together this summer and it just looks like it's clicking.
"Hopefully it will keep going in that direction. Everyone is willing to play well and see their team-mates play well for the good of the club."
Frampton has been in and out of the side all season because of injury and suspension, having to force his way back into the side on a number of occasions despite being the club captain.
The 31-year-old said it a very healthy position to be in.
"It don't expect to come into any place and get my place outright," he said. "I had a couple of injuries and a suspension but I wouldn't come to a club where I didn't have to fight for my place."
