Manchester United have suffered a fresh blow in their pursuit of Borussia Dortmund star Jadon Sancho, who was eyed as a top target for the Red Devils in the summer.

According to Mirror, Borussia Dortmund have warned Manchester United about the unavailability of their star player Jadon Sancho in the summer after it was reported that the English whizkid was identified as a top summer target by coach Ole-Gunnar Solskjaer.

Dortmund’s sporting director Michael Zorc has already clarified that the club will be reluctant to let go of Sancho in the summer, amid interest from a host of top clubs across Europe.

“I’m far from putting a price tag on Jadon,” said Zorc. “He will certainly not play in Dortmund until the end of his career. That is also part of the truth. But I will say that, even for the biggest club in the world, his transfer would be difficult right now. Jadon will play at Dortmund next season and we are definitely planning with him.”

The Black and Yellows have already cashed in on Christian Pulisic, who joined Chelsea for a whopping fee of £58 million – a move that made him the most expensive American footballer in footballing history.

Therefore, it is unlikely that the Dortmund hierarchy will be willing to let go of yet another attacking sensation, especially as they look to continue their push for the Bundesliga title next season.

As for Manchester United, missing out on Sancho in the upcoming summer transfer window will certainly be a blow considering the fact that the England international could have been the missing piece of the jigsaw in the attacking department.

Indeed, Sancho’s explosive pace coupled with his willingness to take on defenders could have proved beneficial for the club, especially when probing the opposition. And the fact that the 18-year-old is also capable of whipping in crosses into the box would have been helpful in setting up the likes of Romelu Lukaku and co.

On the flip side, however, a big-money move to the Premier League may come a little too early for the young Sancho this summer.

The former Manchester City prodigy is still quite inexperienced at the highest level of football, having made only 46 competitive senior appearances with the Black and Yellows this season. This raises doubts on whether or not he will be able to cope with the pressure that is usually associated with any big-money signings for Manchester United.

Therefore, it would perhaps be wiser for Sancho, himself, to remain in Germany for at least a couple of years before making the next step in his career, though United will most certainly continue to keep an eye on this highly talented English international.
