The moment when the UCL starts will probably be a good moment for Juventus, because maybe Inter Milan will start to have to divide their focus. Namely in Serie A and at UCL. So it is possible that Inter Milan will even start playing more carefully in Serie A to avoid injuries to their squad players so they can still perform optimally in the UCL.
This is a possibility but I doubt this will affect Inter. Inter have been playing in the Champions League and the Seria A all season long yet they're still at the top of the table. Inter are highly motivated to win the league title this season and they're in good form.
The Italian Cup win is an extra motivation.
Juventus is also in good form but I feel Inter is better. A difference between them is that Juventus don't have players that are currently hot as Inter Milan players.
Lautaro Martinez is currently on fire and he's leading Inter's attack very well. It's going to be a tough battle for both teams but I feel Inter will win the league.
Even though Inter are still at the top of the Serie A standings and have also completed the Champions League group phase but ya,at least the pressure in the knockout phase later will certainly have a big difference then what happened in the group phase . Therefore, at least any result still has a big chance of occurring in terms of failure and success. Considering,the pressure that Inter is receiving in Serie A also doesn't seem easy at all because ya, the factor about Juventus who only play in the domestic league and also Vlahovic who is currently also in a good trend . So ya, at least, Inter will have big risks and worries in maintaining its position at the top of the Serie A standings in the rest of the season.
