#5 Dan-Axel Zagadou
Another option that Manchester United can take a look at is young Dan-Axel Zagadou. At only 19 years old, he lacks the experience and pedigree to walk straight into the Manchester United back line. Honestly speaking, if Manchester United are to consider a young central defender, they'd look home at Axel Tuanzebe.
But take nothing away from this young French man who has the talent and potential to possibly be one of the best in the world at some point. He already has 13 appearances to his name this season at Borussia Dortmund. If a club like Borussia can trust him to play in three Champions League matches, then he surely does have something special about him.
At Manchester United, he'd probably be the third or fourth choice defender, but that's not an insult to his potential. He'd surely overthrow hos competitors after gaining some experience. That's how much potential the young Dan-Axel Zagadou has in him. He'd also be a great asset because of his versatility as he can slot in at left back as well.
