Finland came close when Robin Lod’s curling shot hit the post, while Oliver Antman’s low shot hit defender Nathan Collins’ post behind the posts.
But the home team scored the decisive goal when Ferguson rose highest to score in Dublin.
It came after some excellent work from Mikey Johnston on the left, and the winger’s cross was met by Brighton striker Ferguson, whose face was a story of relief as he scored his first international goal in over a year following an injury. months.
“It was a beautiful goal,” Hallgrimsson added.
“Especially in the first half I thought we had hurt them on the wings. We moved the ball quickly and got into a one-on-one position. Both Mikey and Festy [Ebosele] he did a brilliant job.
“We should have moved the ball more from side to side to take advantage of the advantage we had.”
While Kelleher’s save against Pohjanpalo was crucial in securing the victory, Hallgrimsson was delighted with his team’s “fight” on the field.
“The energy was there, the enthusiasm was there and the fight was there.
“We were winning duels. These are all factors that will help you win games.”
As for England, who won 2-0 in Dublin in the Nations League opener in September, Hallgrimsson knows the challenge ahead.
Despite a depleted squad that saw nine players withdraw before Thursday’s game in Greece, England won 3-0 but still need victory over the Irish in their final game to secure top spot in the B2 League.
“They’ll need a win to win the group,” Hallgrimsson said with a smile.
“We will do our best in that case.”
