Arsenal are clear favorites in this match, and in addition to having home advantage, they have also consistently won against Nottingham Forest at the Emirates.
While Nottingham Forest has the potential to be a tough opponent and cause a surprise under their new manager, I don't think they can beat Arsenal, and Mikel Arteta won't let that happen in front of his fans. However, Nuno Espirito Santo's departure from Nottingham Forest will provide Arsenal with an opportunity they will capitalize on, and I'm betting on Arsenal in this match.
I predict a 2-0 victory for Arsenal against Nottingham Forest.
This is because Arsenal striker Viktor Gyokeres is in top form, coupled with a solid midfield. Declan Rice, Martin Zubimendi, and Mikel Merino are playing well, orchestrating Arsenal's attacks. Although several key players, such as William Saliba and Bukayo Saka, are injured, the arrivals of Piero Hincapie from Bayer Leverkusen and Eberechi Eze from Crystal Palace, bolster Arsenal's attack in Week 4 of the Premier League season. An Arsenal victory in this match is crucial considering Arsenal dropped three points the previous week after losing to Liverpool.
