Former Tottenham striker Jurgen Klinsmann has given his backing to Mauricio Pochettino.
The USA coach was at White Hart Lane for defeat to Stoke City.
"Every coach needs time to put his mark on an environment, on a club, on a national team programme. Wherever you work, success will only happen over time," said the German.
"Unfortunately, professional football is driven by short-term results, high media expectations and high fan expectations and that often drives clubs to make very quick decisions just because they have lost five games in a row.
"If you want to evaluate the work of a coach then you can only do that over a longer period of time. That's the way it is. In every other working environment you need and get that.
"In order for Mauricio to put his stamp on Spurs he needs a couple of transfer windows to build the team he has in mind, to put the puzzle together that he envisions."
