David Syers is hoping to earn a permanent deal from Bradford boss Peter Taylor by the end of the week.
The 22-year-old midfielder, on trial throughout the summer, is on non-contract terms, but boosted his chances by scoring the Bantams' first goal in the midweek Carling Cup win over Nottingham Forest.
City manager Peter Taylor told the club's official website: "We said we'd make a decision by the end of the week, but he hasn't done himself any harm.
"He's full of energy, he gets about, he makes those forward runs and he got a really important goal for us.
"At the end of last week I said I wanted to look at him for one more week and he hasn't done anything wrong to be fair."
