Pochettino said Rose was one of the first players he spoke to when he took charge of Tottenham, who are second in the table and chasing their first league title in 55 years.
"My idea from the beginning was to give him a chance to show he has the quality to play for Tottenham," the manager said in British media.
"When we arrived it was in a moment that was difficult for him but today I am very pleased for him because he scored and the ground was singing his name."
