The Icelandic midfielder marked his full debut with a half-volley from well beyond 40 yards out that sailed majestically over Hajduk goalkeeper Dante Stipica and levelled the scores at 1-1 on the night.
His strike out of the blue, just seconds into the second half, cancelled out Josip Radošević's own stunner two minutes before the break and effectively put this playoff tie beyond the Croatians who also saw Ahmed Said's penalty saved by Jordan Pickford.
"I saw Gylfi's goal, but I don't think everyone on the bench did," Koeman said. "It was incredible. I don't have any other word for it.
"You need to be really clever to see that possibility and, after two or three weeks of the season, it could be the goal of the season."
The Dutchman also had plenty of praise for Pickford who nipped in the bud any rally by Hajduk in the second half when he guessed right and pushed Said's spot kick away to safety for Michael Keane to hack clear.
"The penalty save was key as well because there were still 30 minutes to go at that time," Koeman continued. "Jordan is showing that we made the right decision to sign him.
"He is still a young goalkeeper and I have been really impressed by what he's done from day one here.
"It is an important position in the team. There's a big future for Everton and a big future for him."
Koeman confirmed that midfielder Idrissa Gueye had been left out of the travelling squad as a precaution after he felt his hamstring slightly following Monday's draw with Manchester City.
With another important away day at Stamford Bridge to face Chelsea on Sunday and Morgan Schneiderlin ruled out through suspension, the club's medical staff were taking no chances with the Senegalese midfielder.
"It was too risky to start [Idrissa]," the manager explained. "He had a scan on his hamstring and everything was fine, but we didn't want to take the risk with Morgan Schneiderlin out of the game on Sunday."

That apart, although his match fitness levels are not yet where they need to be, I thought overall he did ok. Solid start.

Great goal and overall very happy with the team and progress being made.
However is anybody else slightly concerned that there appears to be zero rumours etc about a striker despite big Ron stating we were still after one?

We now have European football, a good selling point to potential candidates. That said, I don't see that many quality options around that we could afford. Benteke probably possible, maybe Welbeck. Neither inspire me greatly.
Great goal. Hopefully getting that so early in his spell with us will boost his confidence. The price tag weighing a little less heavily

Like the 1st half last week, in the last 15 min of the game the passing was excellent, total control. These players seem to be developing a tremendous understanding, plus there's commitment and the team spirit is high.

As for Koeman, I think he picked a decent side last night. I was a bit surprised when Everton tweeted a 442, but once we lined up in 4231 it made a lot more sense. Besic had a good game, perhaps his best in blue (or purple!) and was a lot more disciplined. Schneiderlin was great, all of the back 4 looked solid, except for Williams for the pen and the mixup with Pickford. Pickford was cool and calming. Good save for the pen. Rooney was not blowing so hard at the end of that game, and I bet he ran more in that game than Lukaku ever did playing for us. Sigurdsson did not show any signs of not being fit and ran hard all game. Lookman struggled and Lennon was a big improvement and could well have a role to play seeing as we need pace. Calvert Lewin was clever, and improved again.
All in all Koeman got the job done and the foundations are now laid. Walsh needs to secure a striker, at least, and we could be in for a good season.
I'm still intrigued to see where Sandro, Klaassen, Rooney, and Sigurdsson all play when it's a big game and they're all fit and in form.

Has to be agent nonsense to get him a transfer as a move to China fell through. Unless Ian / Dermot know something the made up rumours section on newsnow doesn't know?! Do you guys know a bit about him judging from the comments you've posted?

It's been said before, and I agree, that maybe we were holding on until we qualified for the group stages. Just my opinion though. As long as don't bring in someone from the Russian league it will be a well needed signing.

Mangala on a season long loan or, dare I say Sakho, who are both left footed CB's. Both were great at their previous (Porto, CP) clubs.

Not sure what that means if anything, probably bugger all, other than we were strongly linked to those two last summer, and particularly Perez.
Not seen any links to Dzeko for a long time, which may be a good thing.

Jimenez's goal scoring record is poor to pathetic but if Walsh and Ronald see something in him then that's fine with me.
I'd prefer Rondon (WBA) over any of the above but I think he's injured at the moment.

Anyway, the results will come and whilst were the underdogs in the Premier League, a couple of signings and who knows. This will be a good season for Everton FC.
