Tottenham vs Arsenal team news: Mousa Dembele out with Kyle Walker dropped for north London derby

Tottenham midfielder Mousa Dembele misses Spurs' north London derby starting XI against Arsenal, while Mauricio Pochettino has selected Kieran Trippier over Kyle Walker at right-back.

Dembele is only fit enough for a place on the Spurs bench, while Walker has to settle for a place among the substitutes as Trippier gets the nod.

Pochettino looks to have reverted to a back four despite having selected a back three in big games this season, while Eric Dier starts in midfield alongside Victor Wanyama as Harry Kane leads the line backed up by Dele Alli.

Spurs XI: Lloris, Trippier, Alderweireld, Vertonghen, Davies, Dier, Wanyama, Son, Eriksen, Dele Alli, Kane
Subs: Vorm, Walker, Wimmer, Dembele, Sissoko, Nkoudou, Janssen

Arsenal XI: Cech, Gabriel, Koscielny, Monreal, Oxlade-Chamberlain, Ramsey, Xhaka, Gibbs, Ozil, Sanchez, Giroud
Subs: Ospina, Holding, Bellerin, Coquelin, Iwobi, Walcott, Welbeck
