Chelsea edged Barcelona 4-2 on penalties was the final outcome, after the two sides had drawn 2-2 in the encounter at the FedExField in Maryland, as nearly 80,000 fans enjoyed an enthralling match.
A superb solo effort from Eden Hazard gave Jose Mourinho's men the lead after just ten minutes, then Oscar almost doubled the lead in the 22nd minute, but struck the post, in what was otherwise a very well balanced half with plenty of chances at either end.
Luis Suarez levelled the game early in the second-half, although his strike created a point for debate, as Zouma appeared to clear the ball off the line. However, the match referee felt enough of the ball had entered to warrant the goal.
After the typical pre-season flurry of changes later in the second-half, Sandro Ramirez lifted a beautiful finish beyond the reach of Courtois, only for Gary Cahill to nudge in the 2-2 equaliser for Chelsea.
In the end and to marry with the American audience wanting a definitive outcome, it was Chelsea who were more clinical from the spot, winning the penalty shoot-out 4-2.
Following the game, Barcelona manager Luis Enrique offered his conclusions. In comments via Spanish outlet AS, the Asturuan coach explained: "We didn't lose the game, we drew. It was a game played at a high physical level. We got ourselves in the lead, although there were times when we didn't control the game well enough."
"We leave happy with everything." Enrique concluded, regarding the performance of his team against Chelsea, whilst adding: "I'm sad about the injury for Douglas."
The young Brazilian right-back went down after just 16 minutes and in obvious discomfort, resulting in his removal from the game, with the early signs far from positive about the muscular injury suffered.
Regarding whether his team have missed players like Lionel Messi, Neymar or Dani Alves, who have all been on extended leave, Enrique commented: "Against Manchester United we had a great game. What worries me least of all is the results. We have been at an acceptable level on this tour. In a few days, we'll have everyone back together and for sure, we'll go forward with motivation."
Offering his overall views on the USA tour, particularly the less than impressive displays defensively and , Enrique observed: "All aspects of our game concern us. Football is capricious and we try to defend plays well. We know that we must suffer when we defend corners, because we don't have the tallest players."
Nonetheless, Enrique was keen to point out: "The balance is very positive. We've played against very high quality opponents and we feel very loved by the fans, who have come to see Barça over these days. The local fans are smart for encouraging Barça."
As their pre-season preparations continue, Barcelona are next in action in Italy, when they take on Fiorentina in Florence on Sunday 2nd August. That encounter is followed by the prestigious annual Joan Gamper Trophy match against AS Roma, at the Camp Nou on Wednesday 5th August.
