Arsenal are monitoring RB Leipzig winger Antonio Nusa as the January transfer window approaches, with the club reportedly stepping up their interest in the Norwegian wideman.

The Gunners have identified Nusa as a potential addition to their attacking options, according to reports from ESPN FC's Transfer Talk. The move comes in the context of Arsenal's pursuit of wide attacking reinforcements after failing to land their primary targets earlier in the season.

Nusa, who has established himself as one of the more exciting young wingers in the Bundesliga, has drawn attention from several top European clubs. His pace, directness, and ability to operate on either flank make him an attractive prospect for sides looking to add dynamism to their attack.

RB Leipzig are unlikely to part with the winger cheaply, having invested significantly in developing his talent since his arrival at the club. Any deal for Nusa in the winter window would likely command a substantial fee.

Arsenal manager Mikel Arteta has consistently sought high-quality wide options to complement his side's style of play, and Nusa fits the profile of the technical, energetic attackers the club have tended to target in recent transfer windows.

The January window opens on January 1, giving Arsenal limited time to negotiate and complete any potential deal before the deadline at the end of the month.
