The young midfielder, 18, made his first start at the eighth attempt after his first appearance off the bench in the FA Cup against Burnley last season and six substitute outings this time around.
Josh played his part in a fluent attacking display, combining with Heung-Min Son, Erik Lamela and Clinton Njie in the forward areas to send the French side reeling as Erik bagged a first half hat-trick in the 4-1 victory.
“Ever since I was nine my dream has been to play for Tottenham and this proved how it can all happen if you work hard,” said Josh.
“I had mixed emotions when I found out, excited and nervous at the same time, but as soon as the whistle blew I was ready.
“The moment I stepped onto the pitch I could feel the crowd and when you feel the crowd on your side you just want to do it for them. It was an amazing feeling.”

Josh was determined to cap his first start with a goal - and came so close in the second half when he close-range effort appeared to have beaten goalkeeper Danijel Subasic only to deflect inches wide off the inside of his right foot!
“I was devastated!” said Josh. “I thought we controlled the game though and we finished top of the group, which was the plan.
“It’s time to build on this now. I can only try to go up from here.”
