Tottenham boss Mauricio Pochettino was snappy with reporters today to preview their clash with Newcastle United.

Pochettino didn't take kindly to a question about whether he might experiment with his starting line-up for the home match against Newcastle on Sunday.

"Experiment? I'm not a scientist. I am not a chemist," Pochettino said. "You are talking about experimenting. That is in some room outside of this training room.

"We are coaches and we do our job, we don't experiment. We train people that have the ability to play football. Then that's it.

"Please don't compare us with doctors or people in university studying a lot. I have a lot of respect for the people who do what you say, experiment, to help life, but for us to find solutions, only I am a football coach, far away from the people who work in science or at university. I have full respect for them."
