One of the club's greats, Travis Dodd, suspects it is at least a contributing factor to the team's early-season woes.
But the former Adelaide captain said it was ultimately up to the players to get used to life under their new coach and that the road wasn't blocked to the team climbing off the bottom of the ladder and becoming a competitive force again this season.
Gombau was a dynamic figure on the sideline for Adelaide, wildly celebrating important goals with knee-slides and hugs, and his players appeared to feed off that emotion. Amor is a much more low-key individual who watches intently while he keeps his emotions in check.
"It wouldn't be the only issue, but, certainly, as an outsider looking in, you saw Gombau, running up and down the sideline all day, and now Amor being the complete opposite, very quiet and unassuming," Dodd said.
"It doesn't mean it's a bad way of coaching. You had a coach in Gombau who was so vocal and an extroverted personality, who had a certain way of interacting with the players, and now the players are having to get used to something different to that.
"Players need to be able to adjust to that and I'm sure they will. They've got a lot of experienced players there and it's mostly the same players who were there last season, so they know the football.
"It's just a matter of them finding their groove and confidence and getting back into the swing of things. Gombau and Amor are both Spanish and had great upbringings in the game, but it still takes time for players to adjust to different personalities, as well as any change in playing style.
"They might have the same philosophy and everything like that, but the new coach is still going to have his own style and different training methods. It's going to take some time for players to adjust and get back into the rhythm they had when Gombau was there.
"There's no doubt Amor had a stellar playing career and knows his football. He's now got to get that across to the players and get that to translate into their football on game day."
Amor is a Barcelona great who played 311 games for the club as well as 37 games for Spain, but Dodd feels that as much as the Spaniard knows about the game, it is tough for him to get his point across because of his restricted English.
'The language barrier can be a difficult thing at times," Dodd said.
"I understand Amor is not fluent in English and that sometimes makes it difficult to get messages across in the heat of the moment and when you're trying to get instructions out to the players.
"I think it's going to be a matter of being patient for the players and the fans, because Amor obviously does know his football and it's just a matter of everyone making an adjustment to a different coaching style and personality.
"He said in media that they're keeping possession, but their issue at the moment is that they're not scoring goals. That is certainly the alarming thing at the moment. But, while there is work for them to do, the nuts and bolts are there. It's a matter of getting everything to fit properly.
"And at the end of the day we're in a professional environment where if you're a player you've got to be able to pick yourself up every week and play for pride and play for yourself and play for the team and your mates around you.
"A coach gives instructions and provides you with as much help as possible during the week, but ultimately when players go out there to play it's up to them as individuals to make sure that it comes together and they create opportunities and score goals."
Dodd said he felt there were several other factors contributing to Adelaide not having won yet, including opposition teams being more used to creative players such as Marcelo Carrusca and Isaias and therefore better planning to restrict their influence.
He said it was up to Adelaide to combat that by continuing to evolve and to "make sure they're not becoming predictable and one-dimensional" as a team.
Plus, Dodd said, there was the fact key central defender Nigel Boogaard is now at Newcastle Jets, inspirational captain and goalkeeper Eugene Galekovic is out injured and striker Bruce Djite is still getting match-fit after an injury-delayed start to the season.
"Confidence is a big thing as well and it's hard for that not to be affected if you're having a bad run of results," Dodd said.
"But they're not playing bad football, they're just not scoring goals. If they were banging in half the chances they're creating they would be a lot further up the table than they are at the moment.
"I'm confident that once they get players back from injury and Bruce has got his fitness back it will make a big difference."
