Newcastle skipper Tiote: Form due to new discipline
He admitted his confidence was shattered by the red card he received against Sunderland at the start of last season.
"When you get a red card it is very difficult to come back in and play with the same intensity," he said.
"It really hits your confidence. You think the referee is always going to be looking at you. You become paranoid and fear to make tackles. This year, I have improved and put it right."
