English publication 'The Mirror' reports that Mauricio Pochettino's side remain keen on the former Manchester United man who has refound his best form this season.
Despite the January addition of Lucas Moura, it is reported that Spurs remain seriously interested in Zaha, with a view to a summer move.
However, it appears that there are not alone in admiring the pacey wideman, with Chelsea and Manchester City also said to be keeping a watching brief on Zaha.
Zaha is tied to Palace until 2022, meaning that interested parties will have to splash the cash in order to convince Palace to sell, with a fee of in excess of £50m mooted in some parts.
The Ivory Coast international is currently out with a knee injury sustained against Newcastle, but is likely to feature heavily between now and the end of the cmapiagn as Palace look to avoid relegation from the Premier League.
