Real Madrid needed a last minute winner from new signing Carlos Espi to edge past Espanyol last time out, but were dominant in the game when looking at the underlying numbers - registering an xG of 2.71 from 21 shots. 

Mourinho’s side avoided defeat across all five of their friendly matches, scoring 2+ goals in four of these games. It’s this scoring power that will set Real Madrid apart from most sides in LaLiga this season, especially a Sociedad side who fell to a 1-0 defeat to Real Betis last time out with just nine shots.

Real Sociedad really struggled on the road in LaLiga last season, winning just three of their 19 away matches. They only scored 22 goals across these games, once again suggesting that there is quite a bit of a gap in the scoring power of these sides. 

The first leg meeting between these sides finished 2-2 with Viking managing to upset the odds, and the underlying data, to claim a draw in Zagreb. 

Viking have seen BTTS in five of their last six matches across all competitions, and have notably won all seven of their home games domestically this season - scoring 25 goals in the process (3.57 per game). 

Dinamo Zagreb were heavy favourites to qualify before the first leg, but have since drifted to be the outsiders. They’ve scored in each of their last 13 matches ahead of this clash, notably seeing BTTS in four of their last five matches during Champions League qualifying.
