Manchester United were given a reminder of Liverpool's recent Champions League victory as a plane carrying a banner flew above them ahead of an open training session at the WACA Ground in Perth on Thursday.
Liverpool added a sixth European crown to their collection when they beat Tottenham in the final last month and some were not willing to let fierce rivals United forget in a hurry.
Ole Gunnar Solskjaer's side were preparing to begin a public training session when the banner, which read "Liverpool FC – 6x European champions" was seen overhead.
United face Perth Glory in their first pre-season friendly on Saturday before taking on Leeds next week.
