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.
They will definitely be a priority between the domestic league and the Champions League being the same priority, especially Arsenal are currently also in a bad situation in the Premier League because they have had bad results in the last few matches, they are now in 4th place in the standings and they definitely don't want to be knocked out of the top 4 at least.
In the Champions League itself the pressure will be even greater, especially after entering the knock out round. Every match becomes very important, because once they make a mistake, then the penalty is eliminated from the competition and must forget the dream of winning the Champions League.
