Parlour has hailed Sokratis as a “good signing".
“Arsenal badly needed to improve their defence following last season and Emery has clearly made that a priority this summer," Parlour told bWIN.
“I think Sokratis is a good signing and he will be a no-nonsense, traditional defender in the mould of Tony Adams rather than someone who wants to play out from the back.
“Sokratis is very experienced and he's a big game player with great leadership qualities.
“The fact he knows [Pierre-Emerick] Aubameyang and [Henrikh] Mkhitaryan so well is a bonus too."
