The Red Devils have clocked up 22,000 miles so far on their world tour after having played four matches—beating Amazulu 1-0 in Durban, South Africa before drawing 1-1 with Ajax Cape Town in the country's legislative capital.
That preceded a 1-0 win in China over Shanghai Shenghua, before a trip to Norway saw United's youngsters go home and the Euro 2012 stars come in, with the senior players simply playing to gain match fitness in a 0-0 draw with Valerenga.
Barca, on the other hand, have had a shorter, if more spectacular preseason campaign, beating Hamburg SV 2-1 in Germany before thrashing Raja Casablanca 8-0 in Morocco, all preceded by a 4-1 penalty shoot-out win over Paris Saint-Germain following a 2-2 draw.
United will aim for a second successive win over Barca, with the Premier League giants having beaten their La Liga counterparts in a preseason friendly last season.
Here is a complete preview of the game in Gothenburg.
