The striker has been linked with several other clubs but has been in talks with Crewe first-team coach Steve Holland and a move now appears close.
The length of the deal, the wages percentage and the bonuses on offer have not yet been finalised, but Dario Gradi is staying confident.
"The lad wants to come," Gradi told the club's official website. "Steve has spoken with him and he is keen to come but there are still some issues.
"Talks with Tottenham are ongoing but they are eager to let him go on loan.
"Hopefully we can conclude the deal before Saturday's game at Bristol Rovers."
