The football managers’ union will be shaking their heads at David Moyes’ admission before his reunion with Manchester United. Moyes is back at Everton and thriving, 12 years after leaving Goodison Park for an unsuccessful stint at Old Trafford. Moyes has turned things around at Goodison Park this seasonGettySaturday saw Moyes go full circle, reuniting with a struggling Red Devils as the new Toffees boss.And it also meant a reunion with his former predecessor. Ferguson was in attendance at Goodison Park to watch his former club take on the Toffees in the Premier League.Speaking ahead of the match with TNT Sports, Moyes said: “Sir Alex [Ferguson] is here and I’ve not got any good red.”As the game began, talkSPORT favourite Ally McCoist labelled it a ‘schoolboy error’.Ferguson was known to enjoy a glass of wine post-match with rivals managers. In fact, it was a long-standing tradition among all Premier League bosses during his time at Man United.After a number of battles with Moyes’ previous Everton side, Ferguson was a key figure in appointing his fellow Scotsman at Old Trafford when his 27-year spell ended. Moyes did not have the same success, lasting just ten months in charge of the Red Devils – who would ultimately go through another seven managers before landing on Ruben Amorim in 2024.One of those failed bosses, Erik Ten Hag, chose to ditch the tradition of sharing a glass of wine with the opposition manager after Premier League matches..Ten Hag explained that he was not ‘friends’ with any rival manager in the top-flight.McCoist could not believe Moyes’ ‘schoolboy error’GettyHe said: “No, colleagues, not friends. There was always a good tradition in English football to meet each other after the matches.“But with all the media now, I think that tradition is a little bit going away. “I think it was a pity because I think it was a nice tradition in English football but that is how football media has progressed.”However, Ten Hag did reignite the tradition somewhat a Man United’s FA Cup clash with Newport County.Ten Hag was seen giving Newport boss Graham Coughlan an expensive bottle of wine picked by Ferguson. Coughlan then admitted he ‘doesn’t drink wine’ and prefers Budweiser. Ten Hag said: “We have a nice gift for you,” to which Coughlan said: “You know I don’t drink wine, I drink Budweiser.”“Really, Budweiser? American beer? But this is a really very good one chosen by Sir Alex so maybe your wife will enjoy it.”
