For several weeks now Premier League players, managers and their staff have closely watched the Bundesliga in the hope of learning something about games behind closed doors.
There has been no shortage of statistical comparisons and the sample size is just about big enough to extract firm lessons.
Should the same quirks be applicable in the Premier League, Chelsea stand to gain from the headline takeaway of home advantage being negated by empty stands.
Since the German top flight resumed only 20% of home teams have won and 51% of away sides have triumphed. Before lockdown, it was 43% home wins and 35% away. Last season it was 45% home, 31% away.
The Premier League runs along a similar breakdown and should it be replicated then Frank Lampard's team stand to gain more than the chasing back behind them.
Chelsea currently sit fourth with United three points behind and Tottenham seven back. Wolves and Sheffield United, who have a game in hand, trail by five.
Lampard's side have shown indifferent form at Stamford Bridge, taking 24 points from an available 45, while matching that points total from one fewer game on the road.
United and Spurs, however, have leaned more on their home form. Ole Gunnar Solskjaer's team have taken 29 points from 45 at Old Trafford compares to 16 from 42 on the road.
Spurs, meanwhile, have 26 points from 42 at home but only average a point per game from their 15 away trips.
Wolves' case would also be strengthened as they have taken 21 points from 14 away games and 22 from 15 at Molineux, while Sheffield United have 19 away points from 13 games and 24 from 15 at home.
On a negative point for the Blues, however, there has been a significant rise in goals scored via set pieces in the Bundesliga post-lockdown compared to before.
That has been a regular issue for Frank Lampard's team this season, though more pronounced earlier in the campaign, and with an increase of close to 10% in Germany's top flight they will be hoping
