Two late goals have seen Arsenal lose 2-0 to Olympiakos in their NextGen Series group match in Greece.
The visitors had the better of the first half as Serge Gnabry and Lorenzo Ebecilio were both off target with their shots on goal.
Gunners goalkeeper Reice Charles-Cook then had to be alert to palm away Dumitru Rikspun's effort.
Soon after the restart Nico Yennaris saw his drive pushed away before Gnabry again fired wide.
Rafail Soukias then pounced with six minutes remaining after Charles-Cook had saved Ioannidis's original strike.
It got worse for Arsenal in injury time when Hector Bellerin was sent off before Lendro sealed the win minutes later with a curling free kick.
