If there was any doubt left if Union SG would really challenge for the title in Belgium, those doubts should be entirely gone now. They already had a healthy lead at the top of the table, when two weeks ago they started 4 straight games against Genk, Club Brugge, Anderlecht and Antwerp - their biggest test of the season to see how legit they really are.
First they beat Genk 2-1 at home, albeit a bit fortunate with an injury time penalty (which shouldn't have been awarded), at Club Brugge they tied 0-0 but had chances to win, then won 1-0 at home against Anderlecht and tonight went to Antwerp and beat them 2-0. That's 10 out of a possible 12 points, and they now lead 2nd place Antwerp by 10 points.
It's looking more and more like Belgium's version of 2016 Leicester. Of course we still have the championship playoffs, and point totals at the end of the regular season get cut in half.. But still, Union never get outplayed, their few losses were undeserved, they can match any top team they play and more often than not dominate those teams. You can't press them, you can't outwork them, they're smart, fast, and they keep running for 90+ minutes. They have insane chemistry, especially their striker duo of Deniz Undav and Dante Vanzeir, they have an extremely intelligent manager. They also seem to have the football gods on their side, I don't think throughout the season they even had one injury or player missing due to covid. Right now, I can't see anyone stopping them from winning it all.
