Barcelona vs Manchester United live stream: Watch 2015 International Champions Cup online (Preview)

Manchester United and Barcelona will try to stay on the winning track in the 2015 International Champions Cup (ICC) as they collide on Saturday at the home of the San Francisco 49ers, Levi's Stadium.

United already have two wins in the tourney under their belt after defeating Club América 1-0 and San Jose Earthquakes 3-1.

Meanwhile Barca, who defeated Juventus 3-1 in last season's Champions League Final to complete their second treble, also opened their campaign with a victory over Los Angeles Galaxy 2-1.

United manager Louis van Gaal is hopeful that in their match against Barcelona, goalkeeper David De Gea will be available for them after he missed their first two matches because of injury.

De Gea has been rumored to be leaving the club and has been linked to a move to Real Madrid.

"I have a good hope that he can play against Barcelona but he was still injured [for the San Jose game]," Van Gaal said in a post-match conference.

He added, "I told David to go stand in the goal so we have a point of direction for my attackers, but don't do anything to risk more injury because we have to build you up. I hope that he can play and I think he can."

Van Gaal also looks to have fewer changes by halftime against Blaugrana saying via their website, "Against Barcelona, I will play for longer with a line-up. I have to select which players are going to play 60 minutes so it is the first selection."

Meanwhile, Barcelona's Luis Suarez is the only player from their famous attacking trio participating in the tournament.

Lionel Messi and Neymar da Silva Santos Júnior are not with the club in their world tour and will not be competing in the 2015 ICC.

Despite their absence, a number of players have stepped up to start for Barca. These include Pedro Eliezer Rodríguez Ledesma who is rumored to leave the club and join United since Van Gaal is looking for a forward to play alongside Wayne Rooney.

The match will be played on July 25 at 1:05 p.m. PDT or 9:05 p.m. BST (4:05 pm EST) and will be shown by MUTV (UK) and Fox (U.S). The game can be watched online through live stream by clicking here.
