Tottenham are on the lookout for a fourth manager in two years after they sacked Antonio Conte on Sunday.
The north London club are looking to bring in a new manager over the summer and Slot is one of the names on Tottenham’s shortlist of targets.
But De Mos claimed that if he was in the Feyenoord coach’s position, he would not be agreeing to join Tottenham given the fact that no manager has succeeded there in recent years.
He stressed that Spurs have turned out to be a graveyard for coaches as the club always seek to protect the dressing room and it is hard to deal with some of the players who have been at Tottenham for several years.
The Dutch coach also pointed out that Daniel Levy is, he feels, a difficult chairman to deal with for any manager.
Asked if Slot should consider joining Tottenham, De Mos said on the Soccernews podcast Twee Viertje: “I would not do that.
“They are a graveyard for coaches, as it has turned out.
“Whoever has been a coach there in recent years, not a single one of them managed to keep their head above the water.
“It is not easy to work with that chairman, it is not easy to work with the players who have been there for so long, from [Hugo] Lloris to [Harry] Kane or [Heung-Min] Son to [Eric] Dier.
“They are a club that protect the dressing room.
“There must be a good squad in that dressing room.
“It is still a difficult thing when you are dealing with a chairman like Levy.”
Fabio Paratici, who was expected to lead the managerial search at Tottenham, is barred from being involved in football for a scandal involving his former club Juventus.
