Also it would be interesting to see Ozil's goal/assists per game average against top teams in his total time here. This season he has a grand total of 1 goal 0 assists against PSG (H), PSG (A), United (a), Chelsea (h), Chelsea (a), City (a), Spurs (h), Everton (a).
But he got 4 goals and 2 assists against Ludogrets, goals against: West Ham, Stoke, Swansea and Assists against: West Ham, Sunderland, WBA, Burnley, Basel. So some think his season has been decent. He needs a strong finish to the season and to show up in the big games we have left.
