Tottenham Hotspur beat Swansea City 2-1 at White Hart Lane earlier today.
Pochettino took over in the summer of 2014, when most of Spurs’ squad were on holiday.
Rose though had stayed around and Pochettino was keen to speak to the full-back, who he felt was low on confidence.
Since the Argentine boss has taken charge the left-back has now been given a new lease of life and his importance to the Lilywhites was further highlighted this weekend.
Rose scored the winner as Spurs came from behind to beat Swansea City to move to within two points of leaders Leicester City at the top of the league.
And Pochettino said: “When I arrived, the first meeting I had with a Tottenham player was with Danny Rose. The players were on holiday, so I called him and asked to see him in my office.
“I was pleased to give him the opportunity to stay here with us. It was difficult at the beginning as he wasn’t very confident, but today I am very happy and pleased for him, and the fans were singing his name.”
Rose has had to win over his critics in recent times at Spurs, but he has fully established his place in the side now.
The 25-year-old competes with Ben Davies for a place on the left hand side of Tottenham’s defence, and he seems to have become their first choice this term.
There is now talk that Rose could force his way into England’s squad for Euro 2016, and he seems to be going from strength to strength under Pochettino’s guidance.
