Leicester City striker Jeff Schlupp will continue to train with Manchester United until the end of the week.
This is his second week at the Premier League leaders. Initially, it was thought he was only stopping for seven days.
City manager Nigel Pearson would not reveal whether the spell would turn into a transfer deal for the 20-year-old striker, who has been used as left-back cover by City this season.
Pearson said: "Jeff is enjoying himself there and he is there until the end of this week.
"It is good experience for him. Whether it becomes more is something for the clubs to discuss. I have spoken to him two or three times and things are going well."
Pearson has previously stated that United were "having a good look" at the youngster.
