Former Arsenal goalkeeper Jens Lehmann has questioned whether Arsene Wenger is still the right man to take the club forward.

Despite working under the Gunners manager during his time in the capital, Lehmann believes that the current setup is preventing the team from achieving success, and has suggested that the Frenchman needs help with footballing matters.

"Is Arsene still the man to make Arsenal successful? I'm not sure," the German told Goal.com.

"I think in the current conditions it will be very hard for them to win something. They have to make changes.

"Sometimes the structure has to be not only on two shoulders, or one man, but sometimes you need to have a couple of people who define, control and monitor the progress of the club and the philosophy, particularly the clubs that are always growing and the demands on managers are growing."

Arsenal have a chance to win their first trophy for nine years when they face Hull City in the FA Cup final on Saturday.
