Former Arsenal striker Ian Wright has claimed that the team is too reliant on Alexis Sanchez.
Sanchez has scored 12 goals in 19 games for the Gunners since he joined the club in the summer, but a disappointing start to the season has seen Arsene Wenger's side slip down to eighth place in the table.
Arsenal's hopes of finishing in the top four were dented again on Saturday evening with a 2-1 defeat at home to Manchester United.
Wright told BBC Sport: "If it wasn't for Sanchez, where would they be now? They are mid-table without Alexis Sanchez. I can't see Arsenal getting in the top four at the moment."
Arsenal are back in Champions League action on Wednesday when they welcome Borussia Dortmund to the Emirates Stadium.
