And the not winning games, of course.
De Zerbi would be nowhere near the conversation except for the handover he got from Potter's Brighton last season. They had 13 points from the opening 6 games under Potter last season. De Zerbi's Brighton got 49 points from 31 points last season - that's a 60 point season, so they would have finished 8th level with Spurs.
Since September of this season, Brighton have 29 points from their past 26 league games. That's similar form to Palace and Brentford. Since Christmas, Brighton have beaten Sheffield United twice, Stoke, Palace, Forest, and Roma (1-0 in a return leg after losing the first leg 4-0). De Zerbi is on a really poor run of form for 7 months and the good run for 12 months, wasn't that great.
