Arsenal must prioritise signing a new left-back when the January transfer window reopens in less than a month.

The Gunners have made an excellent start to life under Unai Emery; the Spaniard has massively galvanised the side since replacing Arsene Wenger in the summer. The former PSG boss strengthened his squad heavily in the summer and will be pleased to see his signings make an immediate impact at the Emirates. The transfer window will soon be open again giving Emery the chance to bolster his ranks further and maintain their fantastic form.

One area that the Spaniard must look to improve is left-back. Nacho Monreal has struggled for fitness and is approaching the end of his career. Sead Kolasinac has failed to replicate the form he showed in the Bundesliga, and it wouldn’t be a surprise to see the Bosnian depart. Signing a new long-term left-sided defender should be a priority.

The ideal addition to the squad could be RB Leipzig fullback – Marcel Halstenberg. Valued at £7.2m by Transfermarkt, the defender has been a mainstay in the Leipzig starting eleven since joining from St Pauli back in 2016. Injuries restricted him to just 14 Bundesliga appearances last year, but the 27-year-old has quickly made up for lost time in the current campaign with some fantastic showings.

Halstenberg is an excellent defender who would add some much-needed stability to the Arsenal back four. The German is a fantastic tackler, winning two tackles per game on average, as well as reading the game expertly, averaging 1.3 interceptions per game in the Bundesliga. As well as his defensive duties, the full-back loves to contribute to the attack and has averaged an impressive 2.3 key passes per game this year, which will be music to the ears of Pierre-Emerick Aubameyang in the Gunners attack (WhoScored).

Halstenburg is approaching his prime and would be a perfect successor for Monreal in north London.
