The case
Arsenal are short at the back: W. Saliba, E. Konsa, B. White and J. Timber are all listed as missing, and E. Konsa and J. Timber were in the last starting XI. Four defenders out is a bigger problem than one replaceable absence, and Leeds scored 9 in their last five, with D. Calvert-Lewin on 3 of their season goals, so they have a striker who can use the gaps. Both teams' recent form runs above the Premier League average of 2.8 goals a match: Arsenal's last five (9 scored, 6 conceded) averaged 3.0 and Leeds' last five (9 scored, 9 conceded) averaged 3.6.
The last five meetings finished 4-0, 5-0, 4-1, 1-0 and 2-1, an average of 3.6 goals, with four of the five at three or more. That is weak evidence alone, since squads change, but it points the same way as the form. We make the over 54% likely, and the 1.95 price implies 51.3%. The edge comes from the defensive absences, which the league average and the price do not clearly reflect, and it is small.
The risks
A controlled home win with two goals or fewer is the main risk. Arsenal beat Leeds 1-0 in one of the last five, and a 1-0 or 2-0 result loses the over. Exactly three goals wins only half, because a 2.75 line splits the bet between 2.5 and 3, and the half on 3 is returned.
Arsenal's attack is thinned too, and the lineups are not out: C. Tzolis, Bruno Guimarães, Gabriel Jesus and Gabriel Martinelli are out, and K. Havertz is questionable. If the XI is cautious, or Leeds defend deep with G. Gudmundsson also out, the total drops.
