Lukaku: Why did Ozil leave Real Madrid for Arsenal?

The Germany international has been criticised for his performances since the record-breaking move from Real Madrid, with below-par displays continuing into the World Cup
Romelu Lukaku has questioned Mesut Ozil's decision to leave Real Madrid for Arsenal in a playful dig on Twitter.

Arsene Wenger brought the Germany international to the Emirates Stadium last summer, smashing the club's transfer record with a £42.5 million move.

After starting strongly at Arsenal, Ozil's form in the Premier League came under question and he has again been criticised for below-par displays in Brazil.

The 25-year-old was one of Germany's poorest performers as Joachim Low's side stunned hosts Brazil in the World Cup semi-final on Tuesday and Lukaku has jokingly questioned Real Madrid's reasons for selling him.

Lukaku was also the subject of criticism at the World Cup and lost his place in Belgium's starting line-up to 19-year-old Lille striker Divock Origi, but did play a key role as Marc Wilmots' side beat USA in the last 16.
