On Tuesday night, Borussia Dortmund booked their place in the Champions League semi-finals with two ex-Manchester United players in the squad.

For Erik ten Hag it’ll hurt to be watching two players he let go reaching the Champions League semi-final on Tuesday.

Marcel Sabitzer and Jadon Sancho were both in the Borussia Dortmund team which overcame Atletico Madrid.

For Manchester United, this will be annoying considering both have been impressive on this run, while the Red Devils struggle.

Sancho may yet return to Old Trafford, with Ten Hag’s future up in the air this summer.

But for Sabtizer, his United adventure ended last summer before he moved to Dortmund – although a year on, he probably should’ve been kept.

But he’s clearly a figure who impacted his United teammates as they’ve responded to his Instagram post.

Manchester United players respond to Marcel Sabitzer

After the 4-2 win over Madrid on Tuesday, Sabitzer took to Instagram with a message to celebrate the win.

He wrote the message: “YEEEEEES! When faces are telling the story”, accompanied by a photo of him and his Dortmund teammates in celebration.

To this post, Sabitzer received numerous responses, some from his former teammates at Old Trafford.

Bruno Fernandes led the responses, as he commented: “Marceeeeeeel!”, followed by a fire emoji.

Diogo Dalot also commented: “Machiiiiine!!”, followed by two clapping emojis and a flame emoji.

Former United man Fred, also commented: “Well done bro”, followed by clapping and flame emojis.

Finally, David de Gea wrote, “On [fire]” and a fire emoji.

Erik ten Hag will be left regretting some midfield decisions

For Ten Hag, the decision to not sign Sabitzer and to sell Fred will surely be two calls he’s since regretted.

This season has seen the midfield extremely thin, with Casemiro struggling, and Kobbie Mainoo being the only real performer.

Fred in particular would’ve been perfect next to Mainoo, with the burden of building out from the back lifted.

Fred’s work would’ve been so valuable right now, considering how bad Casemiro has been at this.

Annoyingly, Fred has also been tearing it up in Turkey which makes the decision to sell look silly, especially as it effectively just funded the move for Sofyan Amrabat.
