According to Het Nieuwsblad, Christos Tzolis is being watched by several wealthy clubs, including Borussia Dortmund. Tzolis currently has a contract with Club Brugge until 2029. Club Brugge is only willing to cooperate with a transfer after the season, unless an offer that cannot be refused is made. Tzolis stated to VTM that he would only depart for a significantly larger club and does not exclude the possibility of staying for an additional year.

Voetbalnieuws.be has reported that Borussia Dortmund is interested in Christos Tzolis. Club Brugge does not want to lose the Greek international during the season and is unwilling to sell him. However, a record offer of 40 million euro could lead the club to reconsider its position.

Top clubs like Borussia Dortmund are now actively trying to sign Tzolis. According to sources close to the situation, discussions have advanced beyond casual interest. A guideline price of around 45 million euros has been mentioned. CIES estimates his market value to be between 47 and 54 million euros. Tzolis and his representatives are willing to consider a transfer if the sporting conditions are suitable, and there is no attempt to force a transfer or apply public pressure.

Interest from Borussia Dortmund was confirmed. It was reported that there was discussion of a potential bid of up to 45 million euros from Signal Iduna Park, but this reporting was described as extremely premature. According to 'TransferNewsLive', Dortmund closely scouted Christos Tzolis in the Champions League. The source also stated that the club, currently third in the Bundesliga, submitted a request to be informed if concrete offers arrive, so they can decide whether to submit a counter-offer.
