Petko Hristov's agent, Plamen Peychev, mentioned that Hristov is very committed to Spezia but dreams of playing in Serie A. After losing the playoff final against Cremonese, Hristov expressed his desire to stay in Liguria and attempt another promotion to Serie A. However, he is open to evaluating offers from Serie A or abroad. Hristov has a contract with Spezia until 2028, and coach Luca D'Angelo has expressed appreciation for him.

Petko Hristov is currently the captain and a key defensive player for Spezia. There is interest from two unidentified Serie A clubs, but Hristov has expressed his desire to prioritize staying with Spezia, even if it means rejecting offers from higher categories. There is a unilateral release clause in his contract valued at 4 million euros, but this option is considered hypothetical due to Hristov's commitment to Spezia. Transfermarkt currently estimates his market value at 4.00 million euros.
