BERLIN, July 21 (Xinhua) -- Bayern Munich came from behind to beat Paris Saint-Germain 3-1 in the International Champion's Cup on Saturday.

Both sides started highly motivated into the preseason fixture and staged a lively opening period.

PSG opened the scoring with 31 minutes played when Timothy Weah danced through Bayern's defense to slot home into the far post corner to past goalkeeper Sven Ulreich.

Bayern remained unimpressed but they only had to wait until the hour mark as Javi Martinez headed home Arjen Robben's corner to restore parity.

Niko Kovac's men gained momentum and secured the lead eight minutes later as Renato Sanches unleashed a well-taken free kick to make it 2-1 on the scoreboards.

However, the defending Bundesliga champions were not done with the scoring and added another goal to seal the deal when youngster Joshua Zirkzee tapped home Serge Gnabry's cross in the 78th minute.

"The young players work very, very well. That's what they showed on the pitch today," Bayern's defender David Alaba said.

The German giants will travel to the United States for another two test games against Juventus and Manchester City.
