Roy Keane has brought a new intensity to Aston Villa’s training according to Charles N’Zogbia.

Keane’s updated autobiography makes a series of controversial claims which has put the Manchester United legend firmly back in the spotlight.

Keane admits to having a “self-destruct button” and reckons he has been suffering a “mid-life crisis” for years.

N’Zogbia reveals Villa’s squad quickly experienced the Irishman’s no-nonsense style after joining up with Paul Lambert as the club’s new assistant this summer.

But with Villa 10th, N’Zogbia,28, who joined the club in July 2011, insisted: “Yes he is good. He has taken to us at training.

“He does a lot of watching us train. Sometimes when it is not good enough he tells us we have to keep working more and harder.

“That is good for us and for the young players to have him there to make sure we focus on what we have to do.”

Keane was axed by both Sunderland and Ipswich as manager but N’Zogbia insists he has been a great addition for Villa.

N’Zogbia added: “Roy Keane has been playing many years at the top level in the Premier League.

“He is an elite player so you have to learn from him to ensure you perform well.”
