Jose Mourinho has indicated that Tottenham's defensive woes have made it impossible for him to know his best line-up at the back.
Spurs' surge up the table under Mourinho has been undermined by a weak defence and that was on show again against Norwich as they gifted the bottom-club two goals in a 2-2 draw.
Mourinho began the game at Carrow Road with a back three, but hooked off Juan Foyth and Jan Vertonghen at the break, while Serge Aurier, who scored an own goal, and Toby Alderweireld also had poor games.
While the Portuguese is in no doubt about his attacking options, he says performances have made it difficult to be so sure at the other end.
Canaries skipper Grant Hanley says that the video replay system has changed the game.
"It's a strange feeling, you work so hard to get a couple (of goals) up against a team like Spurs and you're looking at the board and thinking, 'Oh no, what's the outcome going to be?' but that's the game today," Hanley said.
"That's how it's developed, that's how it is and it's not going to change, so as a player you have to take it as it comes, stay focused on the game in hand."
