It's a good job Manchester United are off to a flying start this season.
Because their manager, Jose Mourinho, has risked the wrath of the club's fans by meeting Liverpool supporters in Moscow - and even taking one of their badges.
United and Liverpool are both in Moscow for Champions League matches this week, Liverpool playing Spartak Moscow tonight (Tuesday September 26) and United meeting CSKA 24 hours later.
The unusual fixture combo has led to concerns about clashes between the clubs' supporters, who have been warned of strong reprisals from Russian police if they land themselves in trouble.
But some Liverpool fans have clearly seen the funny side of the situation, and took the opportunity to get one over on their arch-rivals when they saw Mourinho at his Moscow hotel.
They posed for a photograph with the Portuguese manager, and even gave him a Spirit of Shankly badge - which is worn by members of Liverpool's supporters groups.
It's surprising that Mourinho even agreed to the photograph - although, in fairness, he doesn't look particularly happy in it.
