Former Arsenal defender Martin Keown has not held back in his criticism of Gus Poyet's time at Sunderland.
The BBC pundit was taking part in his weekly 'Tackle Keown' session on the Daily Mail's website and slated the job Poyet oversaw at the Stadium of Light.
Keown stated that the Uruguayan had 'lost the plot' towards the end of his spell on Wearside and even suggested that he was the exact opposite style of manager to that which the squad would have enjoyed working under.
"Gus Poyet had lost the plot by the end," Keown stated. "He committed the cardinal sin by falling out with the fans.
"Sunderland have gone for a stable, calm individual in Dick Advocaat. If you look at their previous managers, that’s not been the case. They’ve had Roy Keane, Paolo Di Canio and Poyet. Poyet may have seemed calm compared to the other two, but he’s got similar characteristics.
"You want your players to be managed by someone stable and consistent. These three managers were on the edge and were hot-headed."
Poyet's time at Sunderland was brought to an end after the Black Cats' 4-0 defeat to Aston Villa last weekend and appeared to be a decision that had to be made.
Most Sunderland fans had grown frustrated with Poyet's approach and the hope is that his successor, Dick Advocaat, can now galvanise the group.
The Wearsiders are low on confidence, but there is a more positive atmosphere around the Stadium of Light following Poyet's departure and the team need to capitalise on this.
At the moment Sunderland are just one point above the bottom-three and it is hugely important that they start picking up wins on a more regular basis if they are to stay in the Premier League.
