Arsenal legend Nigel Winterburn says they must hold a summer clear-out.
Wenger needs to be backed the board in the transfer market, insists the former fullback.
Winterburn, who played 584 times for the club, said: "Arsenal are struggling to keep up and I think there will have to be changes this summer.
"Arsene Wenger now needs the backing of his board, we need to hear from them saying 'this year we have significant funds'.
"The squad needs improving, but I still believe Arsene is the right man if he gets money to spend."
