Tottenham boss Antonio Conte admits he's trying to change the club's culture.
Conte was speaking to local reporters in Israel today.
He said, "As I've said before, our project, our plan is to try to become competitive, more than the past, but you know very well that in football you build something important in one day, one month, one year you have go step by step and try to increase the quality, increase the number of players in your squad.
"Don't forget that when a team stay in the top four and play European games you need to face four competitions in the best possible way.
"To do this you need a good squad with good quality. We are trying to do this but we have just started this process. Last season I think we worked very well to reach a place in the Champions League. At the same time I think we exploited problems, United's problems and in the last three games Arsenal were four points up on us and for this reason we have to continue with the club to build with the players, to continue to improve them.
"They have a lot of space for improvement. This is a young team and we can work for many years together to improve and fight with the best teams in England and in Europe."
