When an attacking side accelerate play, it is common for the defending team to drop back in an urgent manner, looking to protect their goal.
When this happens, space opens up in front of the defence, for late-arriving midfielders or clever strikers that drop back.
Again, Marmoush has tried to do this on a number of occasions but has not always been found.
This may be a matter of players requiring time to gel. For Savio, it may also be a wide player struggling to pull the ball back on their weak foot.
Left-footed right-winger Savio is better at getting to the byeline but the left-footed Udogie and Robertson have created clearer chances via crosses.
At Marseille, both right winger and right full-back were comfortable cutting the ball back on their right foot.
These crosses were maximised by the excellent box-movement of 37-year-old Pierre-Emerick Aubameyang.
