After a back and forth this summer with Panathanikos for highly-thought-of winger Charis Mavrias, a deal has finally been concluded which will see him spend his foreseeable future on Wearside.
The 19-year-old has signed a 4-year deal at the Stadium of Light, with a fee estimated to be around £2m, The latest reports from Greece indicated there will be a small payment up front, and further add-ons which will make up the remainder of the price.
