Don't underestimate Royale Union Saint-Gilloise, which only since last season started playing in European cups. In its debut European season, the team reached the 1/4 playoffs, passing Ajax and Union Berlin. And this season the team is also very successful.
It is not quite usual to see Eintracht Frankfurt in this tournament, as the team recently won the UEFA Europa League. But after that triumph, things have only gotten worse for Eintracht, and this season the team even barely made it to the League playoffs.
Royale Union Saint-Gilloise is nominally the favorite, but still Eintracht is quite a dangerous opponent. We expect to see goals in this gyre, as Royale Union Saint-Gilloise likes to demonstrate an aggressive style of play not only in the Belgian championship, but also in the European Cup, Eintracht also has no problems with efficiency.
Prediction: at least 3 goals to be scored. We recommend the "Over 2.5" bet, odds 1.92
