Jailed Brazilian defender Breno could return to Bayern Munich, according to the head of the prison in which he is housed.
The 24-year-old was jailed for over three years last July after being found guilty of setting fire to his Munich home.
He was arrested and charged after his home in Munich's luxury Grunwald district was burnt down on the day he learned he needed another operation on his injured knee, having spent two years struggling to recover from torn cruciate ligaments.
However, his conduct over the first year of his jail term has led to considerations to allow him day release, potentially enabling him to play football again.
"We are still in exploratory talks, discussing with the foreigners' registration office and the law enforcement attorneyship," said Michael Stumpf, head of the Munich prison where Breno is being detained.
Should day release be granted, Breno would be free to go and train with a local football club, as long as he returned to prison by an agreed time in the evening.
According to Stumpf, Breno's former club Bayern could well be a taker.
"We are in contact with the club," he told the Welt newspaper. "Once all talks have been concluded, then we will have to see if anything can come of it.
"Bayern could well be a future employer."
The 21-year-old scored 12 goals last season, leapfrogging Darren Bent in the pecking order at Villa Park and breaking into the Austria team.
"I'm really happy that I've signed. I love the club and it's been brilliant for me, for I have a feeling of being at home here at Aston Villa," he told the club's official website.
Weimann has progressed through the club's academy, having moved from Rapid Vienna as a 15-year-old.
He showed his potential during a loan spell with Watford in the 2010-11 season and scored his first senior goals for Villa at the end of the following campaign.
He added: "I've been here for six seasons now, having started with the academy in 2006, and last season was tremendous for me and terrific for the team the way we played over the second half of a really demanding campaign.
"The last several months of the season we played really well and got better and better as season went on. Hopefully, we can continue on like we finished and that will be the challenge.
"Like the other young players in the team, I want to keep improving as a player and keep pushing Villa as high as we can in the Premier League.
"I feel like I owe the manager and the club because the manager (Paul Lambert) backed me last season after he came in and I have always felt comfortable and really supported at the club.
"The supporters, too, have been brilliant with me and they've really taken to me which I'm delighted about. It means everything to know you have support like that. The whole team feels the same way.
"It's great to be a part of an exciting future at Villa. I'm sure the manager will bring in more new faces to help us and this will make us stronger."
Manager Lambert said: "Andi has shown a great work ethic and that's the big thing about him, along with his quality," said Lambert.
"He has drive and a hunger to succeed and that's vital. That's what we're looking for here at Villa.
"He got a sustained run at it last season and he showed the quality that marks him out as a natural finisher. He definitely knows where the goal is and his performances on that right side, coming off the lines, have been really great.
"Whether Andi Weimann is on 'x' amount of money or not, you'll always get the same player - but we're delighted obviously that we've agreed this new deal."
