Amid freezing rain, flurries, and a biting breeze off the waters of the Humber Estuary, alongside a resolute home side pushing hard for promotion, this presented all the makings of a challenging evening’s task for the visitors.
"We could have added to our tally but the opposition are a strong team and it was a difficult fixture; I am delighted with the performance," the manager stated. "Hull City means a lot to me so it was great to get a positive reception from the fans of fans. The attitude of the lads was excellent."
Liam Chelsea manager holds this place close to his heart, considering part of his family are from Hull and his successful spell in charge of the Championship club. This happy connection was extended with a commanding display from his squad, who ultimately strolled into the fifth round of the famous old competition.
Three days after surrendering a 2-0 lead in the Premier League, there was a hint of fragility about Chelsea going into this potentially tricky cup clash. The capacity home support clearly sensed it too, but the London side navigated the challenge perfectly.
Rosenior made alterations, enacting multiple of them to his XI. The match might and maybe should have been decided long before it eventually was, with both the Brazilian winger and Liam Delap guilty of spurning excellent opportunities to put Chelsea in front in the first half.
However, luckily for the visitors, Pedro Neto was in a much more ruthless frame of mind. He broke the deadlock with a spectacular long-range effort, which acted as the catalyst for his team to take control of proceedings. By full time, they had 4 goals, with the forward netting three of them for a brilliant three-goal haul.
Hull displayed great fight all game, but the clearer opportunities always came Chelsea’s way. The winger should have opened the scoring when he went past keeper Dillon Phillips before unbelievably shooting over. Delap then had a comparable horror incident in front of goal against his former club.
He deflected a Phillips's kick which bounced off the bar, and Delap started to celebrate believing the ball had crossed the line. It hadn’t, and by the time he understood, Hull's defenders had responded to avert the threat.
Delap had his head in his hands after that miss, but he was immensely influential from that point onward, registering 3 key passes. The opening was for the first goal as his pass teed up Neto to score from outside the box. Shortly after the restart, it was two as the forward's set-piece went directly in through Phillips's legs.
Soon after Neto’s second goal, the match was effectively ended as a dazzling dribble from Delap laid on his teammate to slide into an unguarded goal. The hat-trick hero then finished his hat-trick as the provider again delivered the decisive ball for the attacker to calmly convert past a helpless goalkeeper.
At that point, the work Hull had put in in the opening half-hour had been forgotten. Their focus must now return to securing a return to the Premier League under their manager, who rested a number of first-choice players with that goal in mind.
"In my opinion we deserved at least one goal but if we perform like this we will be in a strong situation in the Championship," he said. "Never surrender, maybe in the next matches this can be a good lesson of how we must play."
Hull showed great effort to the final whistle, and they almost claimed a consolation when Lewis Koumas hit a the upright in stoppage time. But this was Chelsea’s night, and another encouraging stride for their recently-appointed head coach at a stadium he is familiar with intimately.
That made for an ultimately routine night's performance, and the FA Cup-shaped signs are positive from here for Chelsea. They have played Hull on three previous times in this competition in the past ten years and on each occasion, they have gone on to make the showpiece. There is still work in that regard, but this was another significant tick for Rosenior.
