Olympiakos have strengthened their squad ahead of the new season with the addition of Sevilla's Enzo Maresca.
The one-time West Brom man has penned a three-year contract with the Greek champions after four years in La Liga.
The Italian had two seasons at The Hawthorns before subsequent moves to Juventus, Bologna, Piacenza and Fiorentina.
Although Olympiakos currently dominate Greek football having won all but one of the last 13 league titles, Maresca knows the pressure will be on to succeed.
"It's a huge challenge for me to play for Olympiakos. They have won 12 Greek championships in the last 13 years," he told the club's official website.
"They want to make a step forward in the Champions League and I will try to help my new team to make it.
"I had offers from Italian and English clubs but I preferred to sign for Olympiakos as they showed me how much they wanted me in their squad."
