Josu Sarriegi Zumarraga (born 19 January 1979 in Lazkao, Gipuzkoa) is a Spanish footballer who plays for Panathinaikos FC in the Greek first division, as a central defender.

After having first appeared professionally with modest Basque teams, Sarriegi joined Deportivo Alavés in 1999, making his first team debuts on 18 February 2001 in a 1–0 away win against CA Osasuna.

After a loan with neighbours SD Eibar in the second division, he played 28 games in 2004–05, as Alavés returned to the top level after two years of absence. In the following season, he was first-choice, but the team was relegated again.

Having missed only two games with another Basque side, Athletic de Bilbao, in 2006–07, Sarriegi joined Greece's Panathinaikos FC in August 2007. On 26 November 2008, he scored the winning goal for the Athens side as it defeated F.C. Internazionale Milano 1–0 at the San Siro, in a UEFA Champions League group stage match.

On 9 July 2010, after appearing regularly during three years, the 31-year old extended his contract for a further two seasons. The following year, after the departures of Djibril Cissé and Gilberto Silva, he was voted by his teammates as the new captain.

Sotiris Ninis (Greek: Σωτήρης Νίνης) born 3 April 1990 is a Greek footballer, currently playing for Panathinaikos. Ninis is a member of the Greek national team. He was born in Albania to Greek parents. His FIFA profile claims he "possesses a dizzying range of skills to go with sublime vision, an electrifying change of pace and fearsome long-range shooting skills". He normally plays centrally as a creative midfielder, but can also play on the right.

Ninis was born to ethnic Greek parents in Himara, Northern Epirus (southern Albania).

Ninis began his career in 2004 as a youngster in Panathinaikos' football academies, joining from great academy of Apollon Smyrnis. During these 2 years, he became an integral part of the Panathinaikos Youth Squad and his coaches believe him to be the next promising talent of Greek football. As a result, on 22 December 2006, the club directors offered him a 5 year contract and just 2 weeks after that day, on 7 January 2007, Panathinaikos coach Víctor Muñoz selected him in the main squad for the match against Egaleo at the Olympic Stadium. His outstanding performance earned him the title of the Superleague Matchday MVP and he immediately became the hottest name in every Greek football quarter. He became the second youngest player ever to wear the club's shirt in a league match, at the age of sixteen (the first was Kostas Antoniou −15 years old- in 1978). In February 2007, he officially rejected a call to play for the Albanian Under-21 national team. On 15 February 2007, Ninis became the youngest player to participate with a Greek football team in a European cup match, against RC Lens in France. On February 18, Ninis lead Panathinaikos in a 4–1 win over rivals AEK Athens in the Olympic Stadium. Ninis scored one goal and assisted two others. On July 6, Ninis signed a professional contract with Panathinaikos.
