Peter Crouch says Arsenal blundered not signing former Stoke City teammate Steven N'Zonzi.

N'Zonzi, who is currently on loan at Galatasaray from Roma, spent six seasons in the Premier League with Blackburn Rovers and Stoke City before joining Sevilla in 2015.

Crouch said, "I have wanted Arsenal to address the defensive balance of their side for years and never understood why they didn't buy Steven N'Zonzi.

"Steven played with me at Stoke and he would have been perfect to provide protection in midfield.

"He ended up going to Sevilla for £7million and it was madness Arsenal allowed that to happen.

"The best sides spot their deficiencies and address them to progress."
