MAURICIO POCHETTINO faces a defensive dilemma ahead of Sunday's North London derby.
Spurs are sweating over the fitness of Kyle Walker-Peters - which could lead to Moussa Sissoko or Eric Dier filling in as a makeshift right-back.
Walker-Peters has started all three of Tottenham's Premier League fixtures this season.
But the 22-year-old is a doubt for the clash against Arsenal after he limped off during Sunday's defeat to Newcastle.
He was hauled off in the 62nd minute and replaced by Christian Eriksen after appearing to injure his hamstring.
Sissoko put in a good shift at right-back for the remainder of the match against the Magpies.
The powerful Frenchman, 30, could start at the back alongside Toby Alderweireld, Davinson Sanchez and Danny Rose.
Alternatively, Pochettino could turn to Dier to solve his problems at the back.
He has experience playing at right-back for Spurs and during his time with Sporting Lisbon.
Dier even made his debut for Spurs in the position in 2014 - when he scored a stoppage time winner against West Ham.
