Manchester United must already begin laying the groundwork for the upcoming summer transfer window.

Signing two midfielders looks to be a priority but the left-back spot is also a hugely problematic area.

Luke Shaw has started every Premier League game this season but has been forced off in the last two matches.

At 30 years old, it is unrealistic to expect Shaw to play every match while maintaining peak performance throughout the campaign.

Tyrell Malacia will leave the club after his contract expires at the end of June. Patrick Dorgu remains an exciting prospect, but he looks far more dangerous when given the freedom to operate in advanced attacking areas.

Diego Leon is still extremely raw and will require time to develop before becoming a reliable option for the United first team.

The Red Devils must look to sign a Premier League-proven left-back capable of making an immediate impact.

In our view, few players fit that profile better than Lewis Hall.

Hall is a supremely talented young defender who already looks completely at home in the left-back role.

Despite being only 21, he has already made 100 senior appearances for Chelsea and Newcastle United.
