MANCHESTER UNITED fans have been left fuming after they spotted what Jadon Sancho did when he arrived at Borussia Dortmund.

The 23-year-old has re-signed for the German giants on loan for the remainder of the season after being exiled at Man Utd by Erik ten Hag.

Sancho left Dortmund in 2021 to sign for the Red Devils in a £73million deal, but has since failed to replicate his form in Manchester.

Sancho has now spoken to Dortmund’s media team about his return to the Bundesliga and said: ‘It’s so nice to be back.

‘Dortmund is like a home to me. This is where my career as a professional footballer started. That was always my dream. I’m happy to be back here again.

‘Of course [I am raring to go]. I want to get started! I think my team-mates will make it easy for me to get started here.

Sancho’s statement made Man Utd fans unhappy:

“A few years ago, Sancho also called Old Trafford home,” a fan sarcastically said.

“Sancho once declared that he would do everything to help MU and this is his way of repaying the club,” the second person commented.

“Go away and don’t come back,” another fan said.

He appears delighted to be back in the yellow and black of Dortmund with the club sharing some clips of him arriving at the training ground to their social media.

However, the smile-filled videos haven’t pleased everyone with many Man Utd fans fuming to see one thing that Sancho did.

The England international was filmed wearing the Dortmund training kit and just moments after returning to the club he was seen kissing the badge.

Fans were seething at the act with Sancho still on the books at Old Trafford and set to return after his loan expires in the summer.

One supporter said: “He never kissed the United badge like this.”

While another added: “What a traitor!”

A third wrote: “Kissing the badge on day one… that’s a violation!”

And a fourth chimed in writing: “Good riddance.”

On his return to the club, Sancho was received with wide arms by his former teammates.

Former teammate Erling Haaland, who tweeted a message of support on social media, was also thrilled with the transfer.

Sancho wasted no time getting back into the action, beginning training with the squad.

The dangerous winger is scheduled to go to Marbella with the rest of the squad for their mid-season training camp before making his debut this weekend.

He re-joins the club after previously making 137 appearances in which he scored 50 goals and registered an impressive 64 assists.

The star also seemingly took a swipe at Erik ten Hag during his first interview with the club when he told Dortmund fans that he: “can’t wait to play football with a smile”.

Sancho’s Red Devils contract runs until 2026 and his parent club are reportedly paying £100,000 of his weekly £290,000 salary while he is in Germany.

While Dortmund will pay United £3m for the loan, which could rise to £3.4m if clauses relating to appearances and Champions League qualification are met.
