Arsenal boss Arsene Wenger is positive Laurent Koscielny will be fit for the derby against Tottenham.

Koscielny could feature in the north London derby on Sunday despite injuring his knee in the 1-0 win over Leicester in midweek.

"The uncertainty we have is about Koscielny," Wenger said.

"The news yesterday was positive."

Wenger confirmed, however, that Shkodran Mustafi is still "two weeks away" from featuring for Arsenal after suffering a thigh injury that has sidelined him since the 3-0 loss away to Crystal Palace earlier this month.
