Erik ten Hag invited Charlton's manager into his Old Trafford office after Manchester United's win on Tuesday night.
United won 3-0 in the League Cup quarter-final against Charlton and there was mutual respect between the managers after the game, as Ten Hag spoke with Dean Holden for five minutes in his office.
Ten Hag shared a beer with Holden, gifted his wife a bottle of wine and also gave the lifelong United fan Marcus Rashford's shirt.
