Paulo Sousa has backed fellow Portuguese Andre Villas-Boas for success at Tottenham - if he is given time.
Sousa told the Daily Mail: "It is difficult for anyone to be Tottenham manager after Harry Redknapp. He is very popular in England and at Tottenham, with fans and players and the media.
"Then you're looking for the right profile of players to set out his own football identity and ideas and this takes time. The method of training will be different to what it was under Redknapp.
"If you get positive results it becomes easier, of course, because the convictions will become stronger but there are difficulties at the beginning of each process.
"I'm sure AVB will achieve success at Spurs if he gets time and support. If you identify all Portuguese coaches - not only Andre - our football education, our methods and ideas, will get success.
"In my opinion, January will be a fair time to judge."
