Bayern Munich manager Pep Guardiola refused a post-match handshake with Caleb Porter after the MLS All-Stars beat Bayern Munich in a pre-season friendly.
Robert Lewandowski gave the German champions the lead in the first half but they were pegged back by the MLS select team, with Bradley Wright-Phillips and Landon Donavon on target at Providence Park, Portland.
At the final whistle Guardiola wagged his finger to say "no" to Porter then refused the offer of a handshake, also the head coach of the Portland Timbers, because he was unhappy at some of the tackling by the MLS players.
Porter followed the Spaniard to the half-way line but ignored him. Guardiola's staff also failed to shake Porter's hand.
However, US Soccer president Sunil Galati later took to Twitter to say that the pair had resolved their differences.
He wrote: "All good with Pep Guardiola and Caleb Porter. With them for nice handshake outside the locker room after the game."
Speaking after the match to ESPN, LA Galaxy striker Donovan said: "I understand he doesn't want his players to get hurt.
"They're not great tackles but they're not the worst tackles I've ever seen and I hope [Bastian Schweinsteiger]'s not hurt."
Schweinsteiger had to be withdrawn after a heavy tackle late in the game.
Bayern now return to Germany where they will face Borussia Dortmund in the Super Cup on 13 August. The Bundesliga season starts on 22 August.
