Utility man Bacuna arrived at Villa Park this summer in a £3million deal from FC Groningen and has made six appearances, scoring one goal.
Normally a midfielder, the 22-year-old has slotted into the right-back berth in recent games and helped Villa keep a clean sheet in the 0-0 draw at Hull City and 1-0 win over Norwich.
Bacuna and Antonio Luna are currently ahead of Matt Lowton and Joe Bennett in the full-back pecking order - and the Dutch Under-21 international admits he is learning from Luna as each game goes by.
"I've started to look at him more now as I'm not originally a full-back but I'm playing there at the moment," Bacuna told the Birmingham Mail.
"I think I can learn from Antonio. He is going up and down all the time - always attacking and defending.
"I will keep improving my own game and maybe I can learn from him."
Bacuna and Luna are seemingly part of Paul Lambert's first-choice defensive line-up, with Ron Vlaar and Ciaran Clark filling the centre-back slots in front of goalkeeper Brad Guzan.
Bacuna has applauded 'good guy' Vlaar, saying: "Ron is a quiet guy but he always wants to win.
"He goes into battle and he doesn't want to lose. He is a really good guy to work with.
"Brad is doing well at the moment. He made some really good saves and when we are playing we feel like we have a guard protecting us."
Clark, meanwhile, has been impressed with Bakuna's recent displays, saying: "He had a nice run against Hull. He puts some good crosses into the box and he's comfortable on the ball.
"He has looked really good when he plays. I think he will still be looking to learn and improve as a player because he is only a young lad.
"He still has a lot more to learn, but he will do that."
