The Spanish boss has certainly had an eventual time at St. James' Park so far.
The Spaniard was brought in as replacement for the ailing Steve McClaren with the North East side mired in desperate trouble at the bottom of the table.
Though he could not prevent their ultimate relegation, the 56-year-old sparked a huge improvement in both performances and attitude on Tyneside, and came within touching distance of proving to be a remarkable saviour.
His decision to stay at the club and sign a new three-year contract despite their drop into the Championship has breathed new hope into Magpies supporters that next season may hold reason for optimism amidst the gloom of a second relegation in eight years.
Here is a photographic timeline of Benitez's dramatic time at Newcastle so far.
11 March - The former Real Madrid manager is appointed to replace McClaren.
20 March - In their second match under Benitez, Newcastle's end their long losing streak against arch-rivals Sunderland thanks to Aleksandar Mitrovic's late equaliser.
2 April - Benitez and Newcastle suffer a devastating blow with a hugely damaging last-gasp 3-2 defeat to fellow strugglers Norwich City.
16 April - The mini-revival begins as Benitez steers the club to a first win since early February with a convincing 3-0 victory over Swansea City.
19 April - They then build upon that result with an impressive home draw with high-flying Manchester City in a game they could really have won.
23 April - Another hugely positive step came at Anfield, when they recovered from 2-0 down against Liverpool to draw 2-2.
30 April - Andros Townsend's superb free-kick gave the club genuine hope that they might pull off a miraculous recovery by securing a 1-0 win over Crystal Palace.
7 May - However, their failure to beat hopeless already-relegated Villa at Villa Park proved to be the nail in their coffin, allowing Sunderland to seal their fate with a win in their game in hand.
15 May - Despite that bitter end, the season finished on an astonishing high with the 5-1 thrashing of high-flying Tottenham on the final day.
25 May - Following their relegation, Benitez ended speculation over his future by signing a new three-year deal.
