The 28-year-old centre-back joined the club from Bournemouth last month on a three-year deal.
Tommy Elphick has only been an Aston Villa player for three weeks after arriving from Bournemouth last month for a reported £3.6 million fee, but he has clearly already made a big impression on new teammate Jordan Amavi.
Speaking to Villa’s official website from their preseason training camp in Austria, the Frenchman was quick to lavish praise on his fellow defender and noted how he has wasted no time in establishing himself as a leader in the dressing room.
The former Bournemouth captain has also enjoyed success in the Championship before, having skippered the Cherries to promotion in 2015, and Amavi believes that experience will prove invaluable to Villa’s bid to return to the Premier League at the first time of asking.
“Tommy is a good player. I have seen that already in training,” the left-back told avfc.co.uk. “There are so many positives with Tommy. He is a leader. You can sense that straight away.
"He is a good guy and has settled in very quickly and, from a football perspective, he has Championship experience from his time at Bournemouth which will be so, so important for us.”
New Villa manager Roberto Di Matteo also completed his second signing of the summer on Friday, bringing in 21-year-old Italian goalkeeper Pierluigi Gollini from Hellas Verona for a fee believed to be around £4.25 million.
The Italy Under-21 international made 26 appearances in Serie A last season and, while he was unable to prevent the Vento-based outfit from suffering relegation, his performances throughout the campaign still earned him plenty of plaudits.
He also has previous experience of English football, having spent two years at Manchester United between 2012 and 2014 before joining Verona, and Amavi thinks the former Red Devils prospect is destined for a bright future with the claret and blues.
“Tommy Elphick and Pierluigi Gollini look so alike, I’d swear they were related,” the France Under-21 international said. “But joking aside, they are very good additions to our group and I believe both will help the squad very much.
“Pierluigi only joined us over the past couple of days so I haven’t seen much of him on the training pitch but he is clearly a player with a big future. He will only get better.”
Elphick and Gollini both made their debut for Villa in Saturday's preseason opener against Austrian lower league side Grazer AK, playing the first half with Elphick wearing the captain's armband as Di Matteo's men romped to an easy 8-0 win.
Amavi did not feature in the match, however, as he has only just returned to full training from the cruciate knee ligament injury which forced him to miss the majority of last season following his summer move from Nice.
The 22-year-old defender is ahead of schedule in his rehab, though, and should be back in action by the time the claret and blues kick off their Championship campaign at Sheffield Wednesday on 7 August.
"We’ve been back together now for just over a week and I can’t describe the feeling of being with the boys properly after my long time out injured," he added to avfc.co.uk. "For me, I had a very big injury but, after eight months without football, I am here and I feel I am a stronger person having gone through that bad time.
"That often happens when you face adversity, I believe it makes you stronger. I am certainly very happy now."
