Barcelona  resurgence sees them top of the stats but is this fair?

Usual blurb: Teams are ranked by positional value added. This is basically the value added +1  divided by the finishing position. That way higher ranked teams can still rank highly in the stats.

Barca have a PVA of +2.33 and the highest VA of +6 in the league , they beat Hellas who still got a +2 VA and dominated the league. Arsenal on +4 VA were 3rd in the stats with Levante and Espanyol on +5 VA being notable over achievers. Lowest ranked in the stats were the surprising relegated Genoa with -7 VA , Man City and Juventus had -4VA.

Two potential relegation candidates avoided the drop in Leverkusen and Espanyol.
