Groningen have made a hectic start to the season, winning two of their opening six matches and seeing 25 goals across these games (4.16 per game).

They’ve seen BTTS in all six of these matches, most recently earning a point on the road against Go Ahead Eagles in a 1-1 draw but not without conceding an xG of 3.50 from 25 shots.

Zwolle conceded seven goals at home against Feyenoord last time out, winning just one of their opening six matches. They held Groningen to two draws in the Eredivisie last season, with BTTS landing in both matches.

The most recent clash between the sides saw both teams register an xG of 2.0 or higher (2.55-2.48), suggesting that this will be a meeting that produces chances at both ends.

No side saw BTTS more often than Monaco in Ligue 1 last season, seeing goals at both ends in nearly 70% of their matches.

They’ve seen BTTS in each of their last two matches ahead of this clash against Strasbourg and PSG, with only two clean sheets in their six matches across all competitions.

Both league meetings between these sides last season saw BTTS, with the most recent meeting producing five goals as Monaco came away 3-2 winners over Lens with both sides posting a healthy xG (1.79-1.70).

Lens have seen BTTS in four of their last five matches, most recently contesting a 2-2 draw against a newly promoted Le Mans side on the road. 

Chelsea are without a clean sheet across their last 20 Premier League matches.

It’s an issue that’s been present for far longer than Xabi Alonso’s tenure, with Chelsea lacking defensive structure ahead of a trip to a ground where they have historically struggled.

Brentford have made a strong start to the campaign having avoided defeat across their opening four Premier League matches. They’ve scored seven goals across these games, seeing BTTS in each of their last five matches.

This fixture last season produced four goals as Brentford claimed a point against Chelsea in a 2-2 draw. I can’t see Chelsea shoring up their backline ahead of this clash, though they do have the attacking quality to get on the scoresheet.
