Arsenal are accelerating their interest in bringing in a new left-sided forward in the January transfer window, with Andrea Berta stepping up his efforts.

The Gunners have had an excellent start to the season as they sit top of the Premier League table with nine wins from their opening ten games, while they are also undefeated in the Champions League so far.

But Mikel Arteta was desperate to add to his attacking options during the summer transfer window, and saw moves for Morgan Rogers, Vinicius Jr, and Julian Alvarez fail to materialise throughout, with Christos Tzolis the only forward signing that came through the doors at the Emirates Stadium.

Despite their excellent results this season, the team have been lacking an extra push in the final third so far, with Tzolis, Noni Madueke, and Eberechi Eze all filling in on the left wing at different stages of the campaign.

None of them have been able to provide the stardust at the top level, and it has now emerged that the north London club are keen to make additions to their squad in the winter window, with a left-winger still right at the top of their wishlist.

According to a report by TEAMtalk, Arsenal have been watching RB Leipzig star Antonio Nusa at his last three games for the Bundesliga side. The 21-year-old is enjoying a fine campaign, having registered six goals and seven assists in all competitions so far. Those performances have attracted the attention of the Gunners, and they are pushing hard to get a deal over the line for the Norwegian.

Andrea Berta is understood to have set funds aside for a marquee forward signing in the transfer window, and Leipzig are believed to value the talented star at around €80m (£67m).

Talks have already been held with the player's representatives ahead of a potential move to the Premier League. There is competition for his signature, with Bayern Munich also eyeing him, but it's Arsenal who are leading the chase at this stage.

Demichelis: Nusa 'One of the Best in Europe'

Nusa is known for his electric dribbling style and his explosive pace, but he has already improved leaps and bounds over the last 12 months.

A regular alongside Erling Haaland at international level, he has been impressing hugely for Leipzig this season, and manager Martin Demichelis believes he is among the best wingers in Europe right now.

That type of profile is exactly what Arsenal will be keen to add to their squad, and at just 21 he has the profile of the best young players in world football, with huge room for potential and growth too, which will only add to the interest in bringing him into the club.

It's a signing that would undoubtedly excite the fans, and would also improve the squad as they chase a second consecutive league title for the first time in their history, and a first-ever Champions League crown.
