STUART Lewis said Wanderers struggled last season because several squad members didn't want to be at the club.
Blues toiled for long spells last year before a dramatic last day escape, going on a run of one win in 18 matches and another which resulted in a solitary victory from 11 games.
Lewis, who was captain for the majority of the campaign, said a lack of dressing room harmony was part of the cause of the trouble.
The midfielder said the upturn in fortune the side have experienced at the beginning of this season - with Wanderers winning three of their first four matches - was down to having the right characters in the squad.
Lewis said that whereas this time players want to fight for their place in the side, last season some people weren't bothered about being involved in the scrap against relegation.
He said: "We've got a very good spirit, good signings who want to be here - that's the most important thing. Everyone is pulling in the right direction - last year they weren't because people didn't want to be here, not even in the squad.
"Now we've got myself, Blooms [Matt Bloomfield] and Josh [Scowen] who in are in the 18 - good people and good players who want to strive for the right things. We need 18 or 20 of them. You can't have four or five.
"Last year we had a core of people that wanted to do things the right way, but not the whole group. Maybe that's the difference."
Manager Gareth Ainsworth has spoken previously about wanting the right characters in his squad and Lewis said the new arrivals over the summer had the mentality to match their ability.
One of the close season signings, Paul Hayes, is the current possessor of the captain's armband and led by example with a stunningly skilful volleyed equaliser at Stevenage on Saturday.
Another, Peter Murphy, contributed yet another goal from midfield - but Lewis said the attitude they and the other new signings had brought with them had been key to Adams Park being a happier place this term.
The 27-year-old, who made his first appearance of the season for Blues as a substitute at Stevenage, said: "They are players that have good experience and have improved the standard of the team. It was a great goal from Hayesy today and Murph's nipped in with another goal.
"If anything they are good people as well. It's no good being good players and not being good people. That's a key to what the gaffer's been looking at bringing in."
