Olympiakos have completed the signing of Blackburn striker Matt Derbyshire.
Derbyshire arrived in Athens on Tuesday and was quickly put through a medical by Olympiakos.
The English striker passed all his medical exams before agreeing terms on a four-year deal.
Derbyshire revealed his delight at finalising his move, having spent the latter part of last season on loan with the Greek giants.
"I am very happy with this transfer. I wanted to stay at Olympiakos," said Derbyshire.
"I hope to improve myself and become much better next season. I want to score more goals with Olympiakos.
"I am looking forward to going to Austria for the pre-season, it's fantastic the feeling for me.
"I will try my best to help Olympiakos. With hard work and I hope to succeed."
