Former Manchester United keeper Roy Carroll has signed for Olympiakos on an 18-month deal.
The former Northern Ireland goalie, 34, also counts Wigan Athletic, West Ham United, Hull City, Odense and OFI Crete among his former clubs.
"I'm very happy to have joined such a club. It's a real honour to be part of Olympiakos, Greece's greatest team. I will do my best in order to contribute and help our squad accomplish its goals," Carroll told the club's website.
"I'm really looking forward to the Europa League games and my own comeback to European competition.
"I'm hoping that next year we will be playing in the Champions League, because everybody wants to play at the top level. In order to be able to do so, however, we must first win the championship."
Carroll was involved in an infamous incident while playing for Manchester United, when he fumbled a Tottenham Hotspur lob into the net without the officials noticing.
