DALLAS — Roma beat Real Madrid 1-0 Tuesday in a friendly match disrupted by a pitch invasion, with a Palestinian flag being waved among the intruders.

Approximately 20 fans, mostly young men, appeared to overwhelm the security officials.

Players and team officials waited as the intruders were rounded up and removed from the scene. Some players stretched while others just stood with hands on hips as the fans ran past looking for acknowledgement.

Roma veteran Francesco Totti scored the only goal on a cross from the right by Alessandro Florenzi in the 58th minute.

Roma nearly made it 2-0 about a minute later, but Adem Ljajic had a close miss. Real Madrid’s Isco shot just right of the goal in the 60th minute.

Roma’s next game in the International Champions Cup friendly tournament is against Italian rival Internazionale Saturday, when Real Madrid will play Manchester United.

United unbeaten

Manchester United remained undefeated under new Dutch manager Louis Van Gaal after defeating Inter Milan 5-3 on penalty kicks in Pasadena Tuesday following a goal-less draw.

Scouting striker talent for an English Premier League season only 18 days away, Van Gaal gave Ivory Coast striker Wilfried Zaha and Japan’s Shinji Kagawa a look in the second half and kept Javier “Chicharito” Hernandez, reportedly being eyed for a transfer deal to Inter, on the bench until late.

“I am very pleased,” Van Gaal said. “I think we played by far the best match of our sequence of three.”

United, which debuted new blue uniforms, began the US pre-season tour with a 7-0 romp over the host Los Angeles Galaxy last Wednesday and edged AS Roma 3-2 at Denver three days ago.

As a crowd of 61,238 watched, Inter’s Marco Andreolli slammed a shot off the crossbar in the shootout to leave United ahead 4-3 and United captain Darren Fletcher followed by kicking home the decider.

Hernandez, Ashley Young, Tom Cleverly and Shinji Kagawa also scored in the shootout for United, which continues the American tour Saturday against Real Madrid at Ann Arbor, Michigan, where a US record football crowd of more than 100,000 is expected.

Chants for “Chicharito” were rewarded with striker Javier Hernandez’s insertion by Van Gaal in the 78th minute.

Fredy Guarin, the Colombian midfielder for Inter who has been linked to a possible transfer deal for Hernandez, entered in the 84th minute.

Guarin blasted a free kick in the 85th minute that forced a leaping right-handed save by United second-half goalkeeper David De Gea.

Zaha, a 21-year-old winger and former Crystal Palace standout, took the field in the second half hoping to prove he could help the club and missed his best shot on the short side in the 90th minute.

Wayne Rooney and Robin Van Persie are among those who could push Zaha into a loan, transfer or sale but the African says he wants to stay and that Van Gaal has made him better.

“He’s a good manager,” Zaha said. “He will help me discover what I can do.”

But Zaha is realistic as well.

“Something I’ve learned, if you’re not the manager’s cup of tea then you aren’t,” he said.

United had a reunion of sorts with former captain Nemanja Vidic, now playing for Inter.

The 32-year-old Serbian defender spent eight seasons at Manchester United, serving as captain from 2010 until his contract ended last month and he joined the Italian club. — Agencies
