Burton Albion defender Kristian Ramsey-Dixon says he will do everything he can to earn an extended contract.
The ex-pizza restaurant worker, 22, has joined from Midlands Combination Premier League side Continental Star.
He told BBC Radio Derby that boss Paul Peschisolido has said he has six weeks to prove he deserves a longer deal.
"The boss says if I can lose all the puppy fat I have and get my positioning right, he's going to extend my deal. By Christmas time I'll be ready," he said.
"It's a massive difference from training once a week to training every day. It says it all that after one month I've lost a stone.
"I was 15 stone and now I'm 14 stone. I need to lose one more stone and then tone up and I'll be ready.
"It's like a dream come true. It's crazy. I used to go to games in a in a tracksuit now I turn up in a suit. It feels so professional. But I'm not going to change."
