Arsenal and MU have changed so much this season. The Gunners are even now incarnated as strong candidates for the Premier League title and Arsenal will clearly dominate the game more because they are playing at home. However, MU, which is now much more solid, will provide commensurate resistance.
Casemiro's absence is also an obstacle for MU. It will be easier for Arsenal to control the midfield in the match duel later, but MU can spread danger through counterattack schemes that Arsenal must be aware of. I predict this game will end in a draw or Arsenal will win narrowly.
With Manchester United will focusing on defensive play, Casemiro's absence could be very tangible for them. But even more important in this game will be how Manchester United will be able to implement counterattacks today. Rashford has good speed and ten Hag can count on him today, there may not be many chances, so they need to try to convert them. Manchester United was difficult to play with Crystal Palace, and most likely it will be even more difficult with Arsenal.
The counterattack carried out by Manchester United cannot be separated from Casimero's contribution there and this will certainly disrupt the balance of Manchester United when facing Arsenal at this time.
Arsenal with their series of positive results plus playing at the Emirates Stadium is clearly not something easy and is definitely the favorite for now. Even though Manchester United have the same record but the clear difference is playing at home and Arsenal for the midfield they are still quite superior in my opinion compared to Manchester United.
