Charis Mavrias: Sunderland winger joins Panathinaikos on loan
Sunderland midfielder Charis Mavrias has rejoined former club Panathinaikos on loan for the rest of the season.
The 20-year-old Greece international has made just six appearances since signing for the Black Cats from the Athens side in August 2013.
Mavrias agreed a three-year deal under former Sunderland manager Paolo Di Canio, who was replaced by current boss Gus Poyet in October 2013.
Panathinaikos, where Mavrias began his career, are third in the Greek league.
