Arsenal legend Charlie Nicholas says it would be "crazy" for Mikel Arteta not to ask Kieran Tierney about Odsonne Edouard.

Scotland international Tierney played alongside Edouard at Celtic before joining Arsenal last summer.

The Gunners are reportedly keeping tabs on the Frenchman, and Nicholas thinks Arteta should pick Tierney's brain.

He told Sky Sports: 'If Arsenal are genuinely interested in Edouard, it would be a crazy scenario if Mikel Arteta and his staff were not questioning Tierney about the player's qualities.

"When Tierney's fit, he's very much an attacking full-back. He could see Edouard's movement, and he could drill balls into his feet.

"He got quite a lot of assists for Edouard during his time at Celtic, knows the quality of the player and he's improved this season."
