Tottenham are not planning to speak to any managers currently unemployed about their vacancy at White Hart Lane.
Spurs have been searching for a new boss since sacking Tim Sherwood earlier this month after the club finished sixth in the Premier League.
Daniel Levy has not put a timeframe on his search for a ninth manager since becoming Spurs chairman in 2001.
Southampton boss Mauricio Pochettino has been strongly linked with the job along with Ajax coach Frank de Boer.
However, Tottenham's stance would appear to rule out the likes of David Moyes, who was sacked by Manchester United last month, as well as former Swansea boss Michael Laudrup who left the Liberty Stadium at the beginning of February.
Similarly Neil Lennon, who parted company with Celtic this week in search of a new challenge, and ex-Cardiff boss Malky Mackay are unlikely to be in the running.
Periphery foreign contenders such as former Chelsea interim manager Guus Hiddink, ex-Barcelona boss Frank Rijkaard and Italian Luciano Spalletti, who are all jobless, can also probably be discounted.
Bookmakers favourite Pochettino said on 9 May that he will seek answers from Southampton's new board over the direction of the club before committing his future to St Mary's.
Tottenham denied making an approach for De Boer on 30 April while Sherwood was still in charge.
