Arsene Wenger admits Ashley Cole's Arsenal departure was a mistake and came as a result of a "misunderstanding over a few thousand pounds."

The left-back came through the ranks in north London, making his debut in 1999.

Cole was part of Arsenal's Invincibles and had been earmarked as a future club captain.

However he left for London rivals Chelsea in 2006 amid a tapping-up storm that saw the player and the Blues hold secret talks.

He told beIN Sports: "Well, I would say personally, most of the time, the players gave us seven, eight, nine years and left after.

"The younger generation like Fabregas we lost early and would not have loved to lose him.

"The player I think we, internally, it was a mistake to lose was Ashley Cole.
