From the moment that Pompey went ahead in the sixth minute of the game, they never really looked like relinquishing their lead.
And Tom Naylor was delighted with a true team performance that secured a 2-0 victory at Hull to displace the hosts at the top of the League One standings.
Jacob Greaves and Josh Magennis were both credited with own-goals to ensure the visitors got into the festive spirit.
Craig MacGillivray, meanwhile, had to make just one meaningful save and Naylor was pleased with the Blues’ disciplined display.
The skipper said: “The lads were absolutely superb in every aspect of the game – right the way from front to back.
“I think they’ve given both the goals as ‘OG’s, but we fully deserved the win and to go top of the table.
"We’re keeping a lot of clean sheets at the moment and that starts from John Marquis running his socks off up front."
“Raggs didn’t have a clue if the ball had gone in or not for the first. I told him that it had and I know they were claiming a free-kick, but it was quite low.
“That was a great start for us and then the second was massive at that point of the game, while we safely saw things out.
“We’re keeping a lot of clean sheets at the moment and that starts from John Marquis running his socks off up front.
“You can see the work-rate and determination we have to get the three points, with Rasmus coming in and doing brilliantly. He settled in like he’s been there all season.
“We’ve had a big week with games on Saturday, Tuesday, Friday. There’s a couple of days now to chill out and rest the legs before we prepare for Boxing Day.”
Pompey fell away after reaching the League One summit a couple of years ago, but Naylor believes they can get the job done this time around.
He said: “We know what we need to do this season and are determined to get promoted automatically. We want to do it for the fans.
“I’m so confident in this side and it’s a marathon not a sprint. We’ve recovered from a blip early on and deserve to be top.”
