Like the senior team, the Ireland U21s faced Nordic opposition tonight.

But for Stephen Kenny's side, it proved to be a sparkling performance as they thrashed Sweden 4-1 at Tallaght Stadium.

But it required them to battle back from a deficit.

Sweden took the lead on 18 minutes through Viktor Gyökeres and it's a lead the visitors held until half-time.

Second-Half Whirlwind

But the second-half was a completely different story as Ireland U21s blew Sweden away.

Four minutes after the break, Lee O'Connor equalised after good work from Adam Idah down the byline.

O'Connor, who made his senior debut against New Zealand last Thursday, applied the finish to the cut-back.

On 64 minutes, it was Idah's turn to find the net. Again it was a cross from the right flank, this time from Elbouzedi.

Idah took up a similar position to O'Connor minutes earlier before a finish low into the net.

With 16 minutes to go, another recent Ireland senior debutant would find the net.

Troy Parrott ran onto Connor Ronan's deflected ball over the top and finished precisely to make it 3-1.

Ronan would also assist the fourth goal, setting up Zak Elbouzedi to tap in from a low left-wing cross.

The commanding win means Ireland stay top of Euro 2021 qualifying Group 1 on 16 points from seven games.

However, Italy are three points behind and have two games in hand in the best runners-up place.
