Kostas describes himself as a left-back that can both attack and defend. He’s a player that likes to get forward as much as possible.
So much so, the player scored against Motherwell – in just his second appearance for the Club. He netted again in the following game, the 2-0 win against Crawley Town.
He started his career at PAOK, where he made his professional debut at the age of 17.
The player was part of the PAOK side that finished second in the Greece Super League in 2013.
Kostas was in the Greece side that made it to the final of the European Under-19 Championship in 2012 – where they narrowly lost against Spain (1-0).
In that competition he was voted amongst the tournament’s top players – Gerard Deulofeu, Ross Barkley and Paul Pogba also lined up for their nations.
Such was his showing at the European Under-19 Championship, a number of Europe’s leading teams showed an interest in signing him. But it was German side Bayer Leverkusen that came out on top, with Stafylidis joining the Bundesliga club in the summer of 2012.
During his first season at Leverkusen, he made a brief return to his former club on loan.
Kostas has represented Greece at Under-17, Under-19, Under-20 and Under-21 level.
He has also won one senior cap – making his debut for the 2004 European Champions in a 1-0 win against Republic of Ireland.
Kostas cites former Fulham midfielder Giorgos Karagounis as one of his footballing heroes.
He shares his birthday, 2nd December, with Fulham teammate Cauley Woodrow. At 20, Stafylidis is a year older.
