Brandon Williams in 'furious' exchange with Man Utd teammate after being blamed for goal

Manchester United full-back Brandon Williams could be heard swearing at teammate Tom Heaton after he was blamed for conceding a goal before half-time, according to reports.

Dortmund, however, capitalised on some slack defending in the final stages of Sunday's first-half.

In fact, the opportunistic Donyell Malen bagged a quickfire double in the 43rd and 44th minute, with the second goal sparking a 'heated' argument between teammates Williams and Heaton.

As you can see from the footage above, a misplaced pass from Victor Lindelof left the Reds in serious trouble.

An animated Williams can be seen venting his frustration moments later.

Ahead of Sunday's pre-season clash against Dortmund, Williams said he was relishing the chance to prove himself ahead of the new campaign.

"The other pre-seasons I've been injured so I've come back hungry and I'm enjoying the tour, and enjoying getting to know the new players coming in as well.

"It's good to be together as it's about making that team spirit going into the season stronger. It helps when you're on the pitch if you know a player off the pitch as well.

"So it's good to speak to some of the foreign players, getting to know their culture, and even the younger boys who've come up and done really well."

He added: "Those who've come up might be shy so it's important to speak to them and get that relationship. It's been an enjoyable week so far and we've got one game to go.

"You've just got to get ready for the first game of the season. You never know, you might be starting – football can change so quickly so you have to prepare yourself as best you can and get involved with the team."
