Former Manchester United keeper Raimond van der Gouw was invited to watch training at Carrington on Tuesday.
Reds manager Erik ten Hag is from the same area as his fellow Dutchman and the pair know each other well.
Van der Gouw travelled to Manchester to watch the 2-1 win over Liverpool at Old Trafford and took up the opportunity to spend some more time with the boss at our training base.
Van der Gouw represented the Reds between 1996 and 2002, after arriving from Vitesse Arnhem to be Peter Schmeichel's deputy.
He played in some big games for the club, including the 1997 Champions League semi-final with Borussia Dortmund, 3-2 defeat to Real Madrid in the same competition in 2000 and the 1999 UEFA Super Cup final with Lazio.
The giant stopper kept a clean sheet in the last of his 60 appearances for Sir Alex Ferguson's side during a goalless draw with Charlton Athletic.
The 59-year-old must have enjoyed the experience of seeing his former club end Liverpool's unbeaten Premier League run this calendar year and he was one of a number of ex-players in attendance on Monday night.
Former colleague Schmeichel was in the directors' box and Peter's fellow Dane Michael Laudrup, who played for both Barcelona and Real Madrid, was working for the overseas media.
United's players will have been hard at work at Carrington, with attentions quickly shifting to Saturday's lunchtime encounter at Southampton.
