Manchester United is keenly pursuing Lewis Hall, the talented left-back currently at Newcastle United, but they face a significant challenge. To convince Newcastle to part with Hall, United would need to set a new world record for a left-back transfer, which currently stands at £68 million, a fee paid by Bayern Munich to Real Madrid for Lucas Hernandez in July 2019.

Sources indicate that Hall has emerged as United's top target for the left-back position this summer. The 21-year-old player is reportedly interested in making the move to Old Trafford. However, Newcastle's new head coach, Matthias Jaissle, is determined to keep Hall, emphasizing that the club is not looking to sell.

Newcastle's strong position means that Manchester United would likely need to offer around £70 million to even prompt a serious discussion about a transfer. Despite United's willingness to test Newcastle's resolve, the likelihood of such a bid being made is considered low, creating a challenging situation as the transfer window approaches its closing date.

In light of these difficulties, Manchester United is also exploring alternative options for the left-back position. Among the players being considered are Jorge Salinas from Racing Santander, who is also attracting interest from Atletico Madrid, and Alejandro Balde from Barcelona. Additionally, United has been monitoring David Raum from RB Leipzig, Antonee Robinson from Fulham, and Adrien Truffert from Bournemouth.

The urgency for a new left-back remains high for Manchester United, and while Lewis Hall is their preferred choice, the complexities surrounding his potential transfer could lead them to seek other solutions before the window closes.
