Olympiacos el arabi reacts to victory over arsenal
I think there may be a slight issue here!
Olympiacos is a Greek football club, while El Arabi is a Moroccan footballer who has played for several clubs, including Olympiacos. However, I couldn't find any information on a specific reaction from El Arabi to a victory over Arsenal, as Olympiacos has never played against Arsenal in a competitive match.
If you meant to ask about a different reaction or scenario, please feel free to clarify and I'll do my best to assist you!
