Arsenal reportedly have regrets over the signing of Kai Havertz during the summer transfer window.
Aside from scoring the winning goal in the 2021 Champions League final, the forward endured a disappointing three-year period with Chelsea.
A total of 32 goals and 15 assists came from 139 appearances in all competitions, but Arsenal boss Mikel Arteta opted to take advantage of the uncertainty at Stamford Bridge at the end of 2022-23.
The Gunners opted to pay in the region of £65m to secure a deal for the Germany international, who had two years remaining on his contract.
Since his arrival at the Emirates Stadium, Arteta has attempted to convert Havertz into an attack-minded midfielder, rather than using him in the final third.
However, the 24-year-old has put together, at best, a mixed start with the North Londoners, chipping in with just one goal and one assist in the Premier League.
Havertz has made 12 starts and five substitute outings in all competitions, but he has generally underperformed in whatever role that he has been given by Arteta.
According to Fichajes, there are people behind the scenes at Arsenal that have been left hugely disappointed by his performances.
Furthermore, the acquisition of the former Bayer Leverkusen star has already been branded 'a mistake' despite being just three months into the season.
The alleged feeling is that Arsenal could have used their transfer funds more wisely, particularly when they are already blessed with a wide array of creative players.
Instead, Havertz is now tied down to a long-term contract and there is little prospect of Arsenal ever being able to recoup a large chunk of the funds that they shelled out on his signature.
Havertz remains in favour with Arteta, as shown by the attacker completing the full 90 minutes in Arsenal's last three matches in all competitions.
Nevertheless, Arsenal have suffered successive defeats to West Ham United and Newcastle United, leaving his selection in doubt ahead of Wednesday's Champions League encounter against Sevilla.
