The success of Arsenal in the UCL will likely hinge on their ability to balance their priorities between domestic and European competitions. It's common for teams to approach such critical ties with a sense of urgency. Fans will undoubtedly be eagerly awaiting the clash, and the coming weeks will be crucial for both Arsenal and Porto in terms of squad management and strategic planning for these vital encounters.
I think both of them will make very thorough preparations for the match in February, because the Champions League is always a priority for every team that is still there, although every team also does not forget the domestic matches they have every season. However, for the match in the Champions League, it will be more attention for the teams that will compete so that both of them will definitely make better preparations than now, even though they are sometimes tested through their respective domestic matches.
The prestige and money that a club can get if they can win a Champions League match is very tempting even if they don't become a champion because every win will be valued at a very big amount of money, that's why this tournament is one of the assessments for whether a club is said to be successful, especially elite clubs.
Yes, there is still about a month of preparation left for the round of 16 matches, but all the preparations made may be in vain if the players are injured because currently many players are defending their countries at AFCON and also the Asian Cup which lasts for one month, it is even very possible that players will not be able to defend their club in the last 16 of the Champions League if the country they are defending can advance further in the tournament between countries.
