Swindon Town manager Paolo di Canio has not yet decided whether to extend the loan contract of West Ham striker Cristian Montano.
The 19-year-old Colombian has scored once in four games for the Robins and his month-long deal is due to expire next week.
"I want to wait," Di Canio revealed to BBC Wiltshire.
"I don't know if he feels part of Swindon Town. He didn't prove this to me in the past week."
Montano has yet to make a first-team appearance for his parent club but had a successful loan spell at Notts County earlier in the season where he scored four goals in 12 matches.
"Since the first day I saw quality and I was very happy," added Di Canio. "I said this is the player that I want because I want quality.
"By example, in training sessions, every moment they are asking me something - it's even in their body language.
"His body language proved to me that he didn't want to stay. So I don't know."
And Di Canio went on to reveal that Montano will not be in the side to face Port Vale on Saturday - the first time the striker has not played a part since his arrival.
"I have to tell you now that Saturday I won't play him - this is for sure," he added.
"But you never know if he came to me and said 'this is my way to train I want to stay' then maybe I can understand. I'm happy he was here and in 10 days time it will be a decision we will make.
"I must speak with the fella and see what's going on. I know my players now but I don't know Cristian as it's only been two weeks."
