The Greece international found himself on the move over the summer after impressing at the World Cup finals.
Clubs from across Europe lodged offers for the 23-year-old defender, with Olympiakos reluctantly agreeing to sanction a sale.
In the end, it was Serie A outfit Roma who emerged victorious in the scramble for his signature as they parted with a 13million euros fee.
Manolas has, however, revealed that Arsenal and Juventus came close to securing his services, although no formal discussions were held with either club.
He told Il Tempo: “It’s true, Juventus sought me out after the World Cup.
“I could also have ended up at Arsenal. But I never went to London, as it was reported.
“Now, for me, there is only Roma. I’m very happy to have come here.”
