Manchester United are keeping a close eye on two left-back options as they look to strengthen their defensive depth, according to ESPN FC. The club have placed Newcastle United's Lewis Hall and Fulham's Antonee Robinson on their shortlist of targets.

Hall has impressed during his time at Newcastle, establishing himself as a reliable option on the left side of defence. The young Englishman has drawn attention from one of the Premier League's most storied clubs as a result.

Robinson, meanwhile, brings an entirely different profile to the table. The United States men's national team regular has been among Fulham's standout performers, earning a reputation as one of the most dynamic left-backs in the division.

United's interest in both players underlines the club's desire to address a position that has been a source of concern in recent seasons. With options at left-back limited, manager Ruben Amorim is believed to be keen on adding competition and quality to that flank.

Whether the club will move firmly for either Hall or Robinson remains to be seen, but their presence on the shortlist signals genuine intent heading into the transfer window.
