Pochettino added that the change in his title from head coach to manager had not drastically changed his role.
"Last season I was head coach, now manager... In the end it's the same job, because when I was head coach I was involved in all the issues of the club," he said.
"Now it's just they want to nominate me manager. I'm happy but it won't change my position. We agreed it would be good for myself and everyone. Really I was always manager but maybe it describes my job better."
Second-placed Spurs need at least a point in their final game of the season against relegated Newcastle United at St James' Park on Sunday to guarantee finishing above bitter local rivals Arsenal for the first time in 21 years.
