Kevin Mirallas made his second 'debut' for Olympiakos as they saw off bottom club Platanias at the weekend.
The Belgium winger enjoyed two seasons in Greece prior to his move to Everton in 2012 and made his return to the reigning Superleague champions earlier this month when he signed on loan until the end of the season.
And Mirallas played 85 minutes of a 2-0 success that saw third-place Olympiakos – who have a game in hand on their title rivals - close the gap on leaders AEK Athens to just two points.
Another debutant during the latest round of games was Harry Charsley, who made the first appearance of his loan spell at Bolton Wanderers as they lost 2-0 at in-form Brentford.
