The former Villa captain is hoping to re-join his old club after beating leukaemia.
The Bulgarian, 36, made 218 appearances for the claret and blues between 2006 and 2012 until he was diagnosed with acute leukaemia after developing a fever during a 3-0 defeat at Arsenal.
His battle with the illness eventually forced him to hang up his boots in May 2013, nine months after it was announced he was in remission, but he is now back in training with Villa’s Under-21s and wants to re-join the club to help in their bid for promotion back to the Premier League next season.
I'm looking forward to a return to football again," Petrov told Sky Sports. "I've told Aston Villa that I'm ready to start a pre-season with them. Obviously they will always have the first look.
"I've been working close to the idea for a year-and-a-half and I've managed to come a long way. I started gradually with slow runs then I moved to five-a-side and then 11-a-side and half a pitch, then Sunday league.
"I've been given permission to train with Villa U21s for the last four months. We've done a couple of tests in the last two weeks and my fitness is getting close to when I retired. I'm really excited and I understand the odds will be against me."
Petrov first joined Villa from Celtic in August 2006 for £6.5 million, reuniting with former manager Martin O’Neill after winning four Scottish league titles under the Northern Irishman at Parkhead.
After overcoming a slow start, the industrious midfielder went on to establish himself as a firm favourite for his committed performances and was handed the captain’s armband in the summer of 2009 following Martin Laursen’s retirement.
As well as winning the club’s Player of the Year award for 2008-09, he also helped O’Neill’s side achieve three straight sixth-place Premier League finishes between 2008 and 2010 and led the team to both the League Cup final and an FA Cup semi-final appearance in 2010.
Needless to say, he was the type of player that the club are currently desperately lacking, and there is little doubt that supporters would welcome him back with open arms given the reaction on Twitter to his comeback announcement.
Here is how just some of them greeted the news…
Petrov wants to make a #avfc comeback after beating cancer. Our current squad moan that training is too hard...— Andrew Stone (@andrewstone85) April 26, 2016
I would welcome Petrov back with open arms, stick him in the heart of that midfield and his heart will spread throughout the squad #avfc— Chris Bedworth (@AVFCBedders) April 26, 2016
Just imagine if Stan Petrov comes back to play for us. Would be simply amazing. #avfc— Andy Brennan (@silverbrenno) April 26, 2016
In a season full of doom and gloom for #avfc Petrov, is a shinning beckon of hope. Our club needs to show, just some of his courage.— TheEgo (@TheEgoEsquire) April 26, 2016
Not a single doubt in my mind. If Petrov wants to return. Sign him. We need a player who cares. #avfc— jason canham (@jcanham1986) April 26, 2016
Great news about Petrov, being relegated may actually make it easier for him to come back #avfc— Luke Marshall (@marshallavfc) April 26, 2016
Stan Petrov...absolute legend. If he can get up to full fitness, he will be nothing but an asset for us next season #avfc— Matt Genner (@mgmatt1983) April 26, 2016
Amazing if Petrov can come back and play for #AVFC again. We need a proper captain once again.— Jack Grimse (@JackGrimse) April 26, 2016

Would cry tears of happiness if Petrov played for Villa again, especially after what he's gone through. Sign that man up #AVFC— Niall (@NiallBowes) April 26, 2016
All day long I'd take Petrov as player and assistant coach. Absolute no brainer if he's fit enough. TBH I'd play him now! #avfc— Matt D (@everysongsung) April 26, 2016
If Petrov did return, Villa might have to open that stand again! #avfc— Andy (@AndyVilla80) April 26, 2016
We have lacked a leader ever since Petrov had to stop playing. How amazing would it be if he returned. What a story #avfc— Molly Jennens (@m0llyfaith) April 26, 2016
Wish the rest of #avfc had the heart & attitude of Stiliyan Petrov.Would love him to come back & perhaps a cheeky little goal against Derby— Gavin Boswell (@gavinboswell) April 26, 2016
Club captain next season Petrov, a real role model unlike the embarrassment which is gabby #avfc— Richard preece (@awesomefool678) April 26, 2016
Get Petrov in. Make him captain. Play him in a DM position so less running. Play him 1 in 2 games. Perfect. #avfc— Nathaniel Deakin (@ndeakin3) April 26, 2016
Would love to see Petrov back in a villa shirt again. If he can get his fitness back then the quality will still be there! #avfc— Joel Rawlin (@AVFC_Joel) April 26, 2016
Petrov can be that midfield championship general we need. Even if he only fits in 15 games would be vital. #avfc— Sean Kettle (@ketz33) April 26, 2016
