One of the big plus points of Michael Carrick's coaching team is that all the component parts have experience of ultra high-pressure environments, either at Manchester United and Real Madrid, or with England.
So they are all used to scrutiny and used to – sometimes damning – opinion.
Roy Keane has clearly not forgotten the blunt response of Michael Carrick's wife Lisa to his criticism of the former England midfielder, even though it was 12 years ago, and has taken the first available opportunity to fire a cheap shot at her, and then launch into a wider attack on Carrick's coaching team – and in particular Jonny Evans.
Carrick is bound to get asked about Keane – he inherited the former United skipper's number 16 shirt when he joined from Tottenham in 2006 – when he speaks to the media for the first time later.
Then his response will be dissected and then Keane will be asked about it and the circle will continue.
This is what happens as Manchester United manager. Ruben Amorim clearly felt those in charge of the club listened to external opinions too much.
