I believe you're talking about being relegated to Serie B, the second division, as Serie A is the main league, comparable to the Premiersihp or the Bundesliga. Said that, Internazionale Milano (commonly known as Inter) is the only team to have never been relegated from the Serie A to Serie B.
Arsenal have never been relegated from the league in their history.

Arsenal FC have never been relegated from the Premier League but were relegated to the then Fourth Division (modern League Two) in 1913.
Real Madrid Barcelona Athletic Bilbao
Grimsby has been regelated the most.
If I am not wrong, Everton F. C. are the only ones to have never been relegated. Tottenham Hotspurs were never relegated from the Premiership League they never been in the bottom Three and top Four ARSENAL ALSO HAVE NEVER BEEN RELEGATED FROM ENGLANDS TOP FLIGHT. You're wrong about all of those 3. Everton and Arsenal have both, indeed, been relegated from England's to flight (Arsenal (as Woolwich Arsenal) in 1913, Everton in 1930 and again in 1951. It would be ridiculous to claim that Woolwich Arsenal and Arsenal weren't the same club. Tottenham fniished in the top 4 of the Premiership, er, last year.
Arsenal is the only club in the E.P.L.ho have never been relegated, so they have the longest reign in England.
