The 19-year-old only recently signed a new deal with Spurs, so it is not known what the trial with Joe Kinnear`s side will lead to.
The versatile midfielder, who had a loan spell at Swindon earlier in the campaign, will face Bristol City`s second string on Wednesday.
Spurs boss Glenn Hoddle has reportedly been pleased with Marney`s progress, so any move to Kenilworth Road would in all probability be a loan deal next term.
