Arsenal are reportedly interested in acquiring Charalampos Kostoulas from Olympiacos. The player's performances in the Olympiacos first-team and the Europa League this season have caught Arsenal's attention. They view him as a possible enhancement for their attacking lineup. Kostoulas is also on Manchester United's radar, indicating a potential transfer competition between the two Premier League powerhouses as the January transfer window nears. Recognized for his promising future, Kostoulas, who plays as a forward, could meet Arsenal's attacking requirements and serve as a suitable option for Manchester United, who have encountered difficulties with their current strikers.
