Luton boss Rob Edwards will make a decision regarding defender Axel Tuanzebe in the coming days.
The Premier League new boys have been giving Tuanzebe a chance to prove his fitness.
The 25-year-old left Manchester United at the expiry of his contract after 37 first team appearances over several years.
Asked about Tuanzebe by reporters, Edwards said: He has been here and training, it's been one where we can both have a look at each other.
"He's been without a club throughout pre-season while he's been getting fit, so he has been training this week and that's not been one we've hidden away from or anything like that.
"He's looked at us, we've looked at him.
"He's a really good guy, a really good bloke, a leader.
"He's been good around the place and trained well, so we'll make a decision on that and he's involved in that process as well.
"He's got to make sure this next one for him has got to be right."
