The all-action midfielder made 17 appearances for us after making the switch from Bundesliga side Schalke and life at Spurs has been everything the 22-year-old hoped it would be.
"Everything I hoped for has come true. I had a really enjoyable second half of the season here, although it was more of a meet and greet really because everything happened so quickly, on my second at the Club I made my debut at Norwich!" Lewis told tottenhamhotspur.com.
"The time flew by. It really has been an unbelievable spell, the atmosphere at the Lane is fantastic and it’s been a great experience for me.
"I really enjoyed playing with the lads. There is so much quality here and it’s a fight for places because the whole squad is so competitive. It’s so enjoyable playing football with these guys. We had a great season and we’ll improve.
"It’s important for me now to have a summer break as we then meet for pre-season and go to Hong Kong. That will be very important. You adapt more, get to know everyone more and more and that was the only thing I missed when I joined (in January)."
