We take on Fiorentina in the Round of 32, second leg with the scores level at 1-1 after the first leg in Florence last week.
Kieran made his Spurs debut in our group opener against Qarabag in September and has played every minute of our seven games in the competition since.
"It’s been a great experience for me personally because I’ve never played in Europe before," said the flying full-back who hit the winner recently against Watford.
"It’s different - different players, different characteristics. It’s a great experience to travel somewhere like Qarabag and then have to be ready to play again on the Sunday.
"The whole feel about European football is great and I hope we can continue our run on Thursday."
Kieran expects a 'great occasion' at the Lane. "It’s a very exciting game," he added.
"We have an away goal so that’s a bit of an advantage but we expect a tough game, a good performance from them but hopefully we’ll get a result on the night.
"They are a team that likes the ball, they can play under pressure and play out from the back, they did that very well at their place.
"It’s a different game this time, we’ve our fans behind us and I'm sure will be a great occasion."
