Mesut Ozil can be a fantastic player, but he must do better in the big games, claims former Arsenal goalkeeper Jens Lehmann

Former Arsenal goalkeeper Jens Lehmann has
urged Mesut Ozil to add consistency to his
game ahead of the new Premier League season.
Ozil, who signed for Arsene Wenger in a
£42.2million move from Real Madrid in 2013,
has slowly become one of Arsenal's star
performers after a difficult start to life in
London.
Lehmann, however, insists Ozil but show he
can perform consistently as well as producing
in the 'big games'.
He told The Sun: 'Everyone knows he can be a
fantastic player. But you need to be a fantastic
player in the big games'
'You don't need to be a fantastic player in the
small games and mediocre player in the big
games.
'He can definitely do that but now he must
prove it. You need to know how to think and
how to programme yourself.'
'Of course he can improve. You can't get better
on the day that you retire from football - but
you can every day before that.'
