Özil played the full 90 minutes in Arsenal’s surprise 3-2 defeat at the hands of the Greek champions.
“The players we are attracting from the likes of Spain in particular, the Ozils, the Sanchezes, they are not their top-liners, are they?” Owen told BT Sport.
“They are players that are sort of starting, sometimes on the bench, getting brought off in games. We are getting their second-rate players at the moment.”
Özil was unable to provide an assist or goal. The World Cup winner has yet to setup up a goal or get on the scoresheet in the Champions League this season.
Olympiakos strategic advisor and BT Sport pundit Christian Karembeu also criticised Özil’s performance in the 3-2 loss against the Greek giants at the Emirates.
“I am so sorry for Özil he was missing, he did not do anything,” Karembeu said on BT Sport after the Arsenal v Olmypiakos game.
Karembeu did however, underline that Özil is a great player and that he admired him at Real Madrid.
“I know him from Real Madrid he was a key player there but he could not help the team today or deliver some key passes,” he added.
