Aubameyang, Mkhitaryan start vs. Spurs, Aaron Ramsey misses out
LONDON -- Aaron Ramsey has been left out of Arsenal's squad for the North London derby at Wembley because of a slight groin injury, but Pierre-Emerick Aubameyang and Henrikh Mkhitaryan start.
Petr Cech also starts after coming off injured against Everton in last Saturday's 5-1 Premier League win with a calf problem.
Ramsey scored a hat trick against Everton but misses out against Tottenham, with Mohamed Elneny replacing him in central midfield.
Jack Wilshere also returns to the starting line-up with Alex Iwobi dropping to the bench.
Tottenham Hotspur name the same XI that beat Manchester United and drew at Liverpool, with Toby Alderweireld not in the squad after returning in the FA Cup midweek.
January signing Lucas Moura, who scored against Arsenal for Paris Saint-Germain in last season's Champions League, is also named on a strong bench but there's no Fernando Llorente in the 18.
