Raheem Sterling scored the only goal of Liverpool's friendly against Greek side Olympiakos.
The game saw the likes of Emre Can and Lazar Markovic show what they will be offering the Reds in the coming.
This was the scene before PAOK's Greek cup semi-final victory over Olympiacos, which was delayed when a group of PAOK fans set fire to the Olympiacos bench.
Former Manchester United goalkeeper Roy Carroll believes the club's fans may start to lose patience with David Moyes if they sense a trophy drought on the way.
Carroll, who played for United between 2001 and 2005, saw their struggles up close last week when his team Olympiacos beat Moyes' men 2-0.
– Roy Carroll on Moyes' woes
It surprised me a bit, the way Manchester United played against us because, for me, they are a team who want to win every game.
They haven't changed too many players from the side that won the league, but David Moyes has had a tough start.
He seems like a nice guy so I hope he does well, but the fans will have to be patient. I just don't know how patient United fans can be because they don't want to do an Arsenal and not win a trophy for that long, or be like Liverpool and go without winning the league for so many years.
Olympiacos striker Michael Olaitan is in "very good condition" in hospital after collapsing during Sunday's Athens derby against Panathinaikos.
The 21-year-old Nigerian, who recently played against Manchester United in a 2-0 Champions League victory for the Greek champions, collapsed in the first half of Olympiacos' 3-0 defeat to Panathinaikos.
He regained consciousness before being taken to hospital for tests and club doctor Christos Theos now believes a viral infection was to blame.
