Barcelona 1-1 Tottenham: 5 Hits and Flops 

#3 Flop - Kyle Walker-Peters

Baptism of fire: Walker-Peters lost possession and was outmuscled in the build-up to Dembele's goal

It was a memorable evening for the 21-year-old making his Champions League debut here, but not for all the right reasons. He was caught in possession by Dembele after Sissoko's header back toward him didn't provide enough time to control and pass into space under pressure.

Dembele surged forward on a blistering counter-attacking run and made no mistake to open the scoring beyond compatriot Hugo Lloris - all of which happened within moments. It would've been easy for Kyle's head to drop after that mistake and struggle to recover, but to his credit, he did the opposite.

It was his sliding block which thwarted Coutinho early in the second-half and interestingly enough, despite being dispossessed on five occasions, he had the team's best pass accuracy (93.9%) on the night.

Replaced by Erik Lamela on the hour mark as Pochettino knew he needed more attacking impetus, this was was a baptism of fire that will ultimately stand him in good stead for the future.
