Associates of Napoli coach Antonio Conte will be present at the Olympiacos match against Leverkusen to watch 23-year-old Greek goalkeeper Konstantinos Tzolakis. Representatives from Bologna are also expected to be there to observe the player. Napoli's interest is not new, as the club has been closely monitoring the Greek international for almost a year and will use the high-difficulty game against the German team as another opportunity to assess him. Tzolakis is under contract with Olympiacos until 2027 and has also attracted interest from other clubs in Germany, England, and Spain. The goalkeeper joined his current club in July 2019 and has made 21 appearances in Super League 1 this season. His current market value is €15.00m, according to Transfermarkt.
