Arsenal manager Arsene Wenger has suggested that he is concerned by the threat of Manchester United forward Marcus Rashford.
The 19-year-old scored twice in the Red Devils' 3-2 triumph over Arsenal at Old Trafford last season.
Arsenal were boosted by the knowledge that Zlatan Ibrahimovic will be suspended after picking up his fifth yellow card of the season in United's 3-1 win over Swansea City before the international break.
However, Wenger has hinted that he is more worried about the possibility of Rashford ruining their afternoon.
"The guy who killed us last year was Rashford," the Frenchman told reporters in Thursday's press conference. "I watched him against a Danish team in midweek [prior to last season's clash] and he scored and I thought this guy could be dangerous.
"His movement was good and he was strong. He took everyone by surprise."
Since making his debut in February, Rashford has scored 12 goals in all competitions.
