Manchester United defender Luke Shaw says he "hopes" to play for Mauricio Pochettino again.
The left-back spent 18 months under the Argentine at Southampton before switching to Old Trafford in 2014 in a £30 million deal.
Shaw has been on the sidelines under Jose Mourinho for nearly a year. His appearance as a late substitute against Swansea on Tuesday was just his second of the season.
And the 22-year-old's admission about his former boss will only fuel talk about a move to Tottenham.
"I think with Southampton he achieved the impossible," Shaw wrote in the book, "Brave New World: Inside Pochettino's Spurs."
"We were one of the best footballing teams in the league. I do hope that I can play for him again one day. And I think he really wants me to play under him again."
Shaw signed a four-year deal when he swapped St Mary's for Old Trafford, but United are set to trigger a one-year extension that will keep him at the club until 2019.
Meanwhile, sources have told ESPN FC that Mourinho remains interested in Tottenham left-back Danny Rose, who went on record in the summer to say he would welcome a move north after starting his career at Leeds.
Mourinho was critical of Shaw last season, suggesting the England international needed a "better understanding of the game."
Shaw, however, paints a different picture of his relationship with Pochettino.
He added: "He used to call me his son, that's how good our relationship was. I've had lots of ups and downs, but when I was with Pochettino it was only ever up, up, up.
"He made me feel that I was the best. He'd show me clips of my games and say, 'You should do this better'. Not in a horrible way. Not I could have done better, but I should have done better, because he knows I can be better."
