Liverpool were certainly clinical.
But Newcastle will still rue not pressing home their advantage with a full complement of players at 0-0.
Set-plays were wasted.
On the one occasion a delivery from Harvey Barnes picked out the head of Gordon, the forward failed to hit the target.
Digging deeper, Newcastle have had 26 shots in their opening two league games of the season, but Howe's side have managed just six efforts on target and two goals.
Although Osula got on the scoresheet on Monday night, the 22-year-old is still developing and has never started a Premier League game for the club.
However, if Newcastle do not reach a breakthrough in the transfer market in the coming days, the Dane could yet line up against Leeds United on Saturday after the black-and-whites had bids turned down for Wolves star Jorgen Strand Larsen and Brentford striker Yoane Wissa.
It was certainly not lost on Howe that one of the best strikers in the world is still on Newcastle's books – and how the hosts could use the Isak of old.
"The quality of Alex would have made a difference in the team," he said.
But, that said, the team has functioned really well.
"The performance of the players and the team in the two games doesn't happen without every part of the team functioning well.
Goals change games, but we're just dealing with what we have."
Howe admitted he was "not party to the talks that were happening" after suggestions that Jamie Reuben, the club's owner, had held face-to-face discussions with Isak while chairman Yasir Al-Rumayyan is also in town.
But, one way or the other, a resolution to this saga is finally imminent ahead of the window closing on 1 September.
How it is needed.
