Take a look back on the career of the Club's latest signing....
WELL-KNOWN for his forward thinking style of play and rocket of a left foot, Kostas Stafylidis certainly undertakes the role of the more modern day full back.
One of the most highly-rated defender to come out of Greece in recent times, the 24-year-old is the Potters’ second acquisition of the January transfer window, arriving on loan from FC Augsburg.
The Greek international has spent nearly six years in Germany with Bayer Leverkusen and Augsburg after moving to the country from PAOK in the summer of 2012, where he had made his professional first team debut
Born in Thessaloniki, 2.6 miles from the Toumba Stadium, Stafylidis made his first team debut at 17 and after a number of promising performances was at the centre of a transfer to Leverkusen.
The attacking full back was then loaned back to the Greek side for the season where he made a further 24 appearances and helped the club he had represented at every youth level to second in the Greece Super League.
Following the conclusion of the loan, he returned to Germany and remained a Bayern Leverkusen player for the next three years, albeit taking in a season with Fulham where he made 38 appearances for the Cottagers, before making the switch to FC Augsburg in 2015.
After making 15 appearances at the WWK Arena in his maiden season with the club, Stafylidis appeared 26 times for Augsburg last term, making the left back slot his own and chipping in with four goals and six man of the match awards as the side finished in 13th place.
On the international scene, meanwhile, the left back was in the Greece U19 side that made it all the way to the final of the European Under-19 Championships in 2012 where they lost to Spain 1-0 in the final.
However, Stafylidis still picked up personal honours after he was named in the team of the tournament, joining fellow teammate Jesé Rodriguez, Gerard Deulofeu, Nathaniel Chalobah and Paul Pogba.
He has also appeared at every age group for his country, with his exceptional talent seeing him called up for the youth sides earlier than he might have expected after being just 16 when he made his debut for the Under-19 side, while his debut for the 2004 European Championship winning side came in 2012 at 18. He has since gone on to appear 21 times at senior for his country, scoring twice.
Stafylidis is the first Greek international that City have had on their books in the Premier League.
