Arsene Wenger insists he left Arsenal last year in good shape.

Wenger dismissed the idea that his departure - after so long in charge - meant that struggles were inevitable, and appeared to criticise some of the club's decision-making since then.

"I don't think it's a necessity to have that," Wenger said. "When I left the club was in a very strong financial position and they bought many players in-between - they have not all worked out.

"I believe that it's not a question of time. The change can be very efficient very quickly, it's just about the right decision-making and that's all that it's about in football, it's about good players.

"We speak about the success of Liverpool, of course they have a great manager, but you have to say as well that in the last three-four years, they bought the right players."
