A youthful Reds side created little in the way of clear scoring opportunities, with Alberto Aquilani's free-kick palmed away by Ivan Benito in their best effort while striker David Ngog wasted two good chances.
At the other end, Nzuzi Bundebele Toko was denied by a combination of Diego Cavalieri and Stephen Darby - though Toko also went closest to a goal for Liverpool, Benito sparing him the indignity of an own goal.
Philadelphia Union 0-1 Manchester United
United emerged with a victory at Lincoln Financial Field but laboured in their second pre-season frenzy after beating Scottish team Celtic 3-1 last week in Toronto.
Bulgarian striker Dimitar Berbatov nearly extended United's lead, hitting the crossbar from close range in the 80th minute.
Arsenal continued their pre-season preparations with a routine 3-0 victory over Sturm Graz in Austria.
Samir Nasri - who scored in Saturday`s 4-0 win at Barnet - grabbed two goals in the first half to put the Gunners in control.
And Arsene Wenger`s side added a third after the interval through Henri Lansbury - one of seven players to come on at the start of the second half.
Huddersfield 1-0 Blackburn Rovers
Joey Gudjonsson scored a sensational winner as Huddersfield recorded a 1-0 victory over a youthful Blackburn side at the Galpharm Stadium.
Gudjonsson fired the home side ahead in the 17th minute, re-adjusting his feet in mid air before thundering a stunning 25-yarder past Rovers goalkeeper Mark Bunn.
There were further chances at both ends in an entertaining clash, but Gudjonsson`s strike proved to be the winner.
Sunderland 1-1 Brighton
Fraizer Campbell denied Brighton with a late equaliser as Sunderland claimed a 1-1 draw in their pre-season friendly in the Algarve.
Glenn Murray had been the central figure as Albion dominated the first half, seeing an 11th-minute header controversially disallowed, curling a good effort over and failing to convert Elliott Bennett's cross with the goal gaping before he finally broke the deadlock from the penalty spot after Boudewijn Zenden handled just before the break.
Young keeper Trevor Carson had to make a superb save from Murray after Matt Kilgallon's error and the Black Cats then had George McCartney stretchered off, but Campbell provided a silver lining when he stretched to turn in Jordan Henderson's excellent free-kick.
Beijing Guoan 0-1 Birmingham
Garry O'Connor was Birmingham's match-winner for the second match in succession on their tour of the Far East.
The Scottish striker, whose goal saw off a Hong Kong XI on Sunday, scored the only goal eight minutes from time against Beijing Guoan after Cameron Jerome saw his shot parried and then squared the rebound to his strike partner.
Summer signing Nikola Zigic hit the bar in the first half and goal-line clearances denied O'Connor and Liam Ridgewell, though Ben Foster had to be alert to tip a free-kick onto the bar at the other end.
Bolton Wanderers 1-1 Toronto (Bolton win 4-3 on penalties)
Bolton claimed the Carlsberg Cup, after defeating a limited Toronto B-team in a penalty shoot-out.
The Wanderers had taken the lead through Matt Taylor's 28th minute, before's Toronto's Maicon Santos leveled the scores in the dying seconds of the first half.
Both teams made whole-sale changes at the interval, and Jussi Jaaskelainen became Bolton's eventual hero after saving two spot-kicks in the shootout.
