Olympiacos defender Sokratis Papastathopoulous has lauded the character and leadership qualities of Arsenal midfielder Granit Xhaka ahead of the Europa League meeting between the sides.
Sokratis spent two-and-a-half years with the north London side where he made 69 appearances in all competitions. He left them to join the Greek outfit in January after his contract was terminated.
The 32-year-old has since emerged as a key player for Olympiacos at the heart of the defence and he will come up against his former employers in the first leg of the Europa League last 16 tie tomorrow.
