Krastev's return to Zwolle comes with a catch, as PEC has secured a real option to buy the player after this season. This means that if the club decides to make the move permanent, they will have the opportunity to sign Krastev for a three-year period. The player is currently owned by City Football Group and is valued at €3 million, according to Transfermarkt.

Krastev has a history with PEC Zwolle, having played for the club in two previous stints. In 46 appearances for the team, he scored eight goals and provided seven assists. The player is currently recovering from an injury sustained last season while playing for Göztepe in Turkey. PEC's technical director, Gerry Hamstra, is optimistic about Krastev's return, stating that the player's fitness will be crucial to his success at the club.

Krastev himself is excited to return to Zwolle, citing the club as one of his favorites. He has expressed his desire to regain top fitness and play in front of a full stadium. With a real option to buy in place, PEC Zwolle will be hoping to make the most of Krastev's talents for the remainder of the season.
