The former Villarreal almost struck on the day.
Glasner said, "The cherry on top would have been that big chance in the first-half. Then he was a little bit unlucky in the second-half.
"But we could see where he will help us with his positioning between the lines, his understanding of the game.
"He will have to adapt to the physicality and the pace of the Premier League football. But he's not the first one and he won't be the last one who has to adapt.
"He was good, he was dangerous, he had chances and it gives me a good feeling that he will score goals for us.
"It was the same with Uche at the end, I thought he could help us in having a little bit more physicality in our attack. And he was great, he had a big chance as well. I think we could have got a penalty in this situation."
