South African striker Davide Somma is hopeful of re-joining Leeds.
The 28-year-old was released by the Elland Road club at the end of last season after enduring a tough spell that included him missing the entire 2011-12 campaign with a knee injury.
The free agent is currently back training with the Championship club.
"You never know the future and I'm going to do everything I can because I feel I have something to give to the club," he told BBC Radio Leeds.
"I've got about a month of hard running left to do and I think I'm getting close to full fitness again now.
"I've had the last clean out of my knee and it went perfect. I'm just looking forward to playing football and scoring goals.
"I understand why Brian McDermott didn't offer me a new deal in the summer but he said to me 'Get yourself better, get fit and we'll take a look at you'. I'm really grateful for that."
Somma, who was born in Johannesburg but raised in United States, scored 12 goals in 33 league appearances in his first stint with Leeds.
"If I had to go on loan to prove my fitness then that'd be fine," he said.
"My heart is in this country and I want to prove myself here. I feel like I have unfinished business."
