I honestly wish to favour Benfica on this, I see them as a team that will want to utilise their home advantage to the maximum and they have a good squad by the way, this is not to make anyy less of Fernabahce, but only that from my perspective I see that Benfica is at advantage, one in which they are not willing to let slide but Fernabache will make it a tough one for them and be sure to expect a goal from both sides.
In other side, Benfica have advantage after being draw at first leg match and second leg as home match fully support from their fans will more motivate for getting victory and secure one spot at UEFA Champion League season 2025/26. Just remember since season 2015 until 2024 Benfica never absent participants at Champion League although last season eliminated at 16 of round after defeating by Barcelona with goals aggregate 4-1.
Difference with Fenerbahce have absent last several consecutives season participating at Champion League, although still have opportunity during the first leg match being draw and the winner team next match will secure place for playing at Champion League. Actually so excited looking back Jose Mourinho at Champion League and he has much memorize when winning UCL with FC Porto and Inter Milan.
