Juventus legend Alessandro del Piero has admitted his surprise that Real Madrid were willing to sell Mesut Özil to Arsenal, but realises the Spanish club had to make a 'sacrifice' after signing Gareth Bale.
Real Madrid captured Bale from Tottenham in a world record transfer worth £85 million on the final days of the transfer window, before Özil moved to north London with the Gunners for a £42.5 million fee.
Özil has flourished during his short time Arsenal, and Real Madrid president Florentino Perez has come under criticism for allowing the 25-year-old Germany international to join Arsenal.
The former Real Madrid playmaker has scored three goals and provided four assists in his eight appearances for the Gunners, and has led them to the top of the Premier League table.
Del Piero, speaking before Juventus and Real Madrid meet in the Champions League, claimed to have been shocked that Özil was able to sign for Arsenal, but realises Madrid had to balance the books after their acquisition of Bale.
"At first I was surprised [that Real sold Özil]. But I think that they had to make a sacrifice after spending so much on [£85m forward] Gareth Bale," Del Piero told AS.
"In any case, Özil will continue to dazzle me. He is a great player playing in a position that is hard to comprehend."
