Aston Villa has approached Olympiacos for Charalampos Kostoulas, a 17-year-old player who has been drawing attention from several European clubs. The young talent, often compared to Roberto Firmino for his versatility and Gabriel Batistuta for his goal-scoring instincts, was a key player in Olympiacos' Youth League victory last season. In addition to Aston Villa, Arsenal has also shown interest in Kostoulas, highlighting his rising profile in European football.
