O'Neill 'had a go' at half-time in Luxembourg win - Bradley

Conor Bradley made his first start of the season after picking up an injury in pre-season for Liverpool

Northern Ireland defender Conor Bradley said that manager Michael O'Neill "had a little bit of a go" at his players at half-time in their 3-1 win against 10-man Luxembourg.

O'Neill's side went in level at 1-1 at the break at the Stade de Luxembourg after Jamie Reid's opener was cancelled out by Aiman Dardari.

And Bradley believes an animated half-time team talk from O'Neill sparked an improved second-half display from NI, which yielded two more goals from Shea Charles and Justin Devenny and a precious three points to start their World Cup qualifying campaign.

"We started the first half really quick, and it was the same second half. Michael had a little bit of a go at us at half-time, it wasn't good enough, rightly so, but we came out all guns blazing second half," he told BBC Sport NI's Gavin Andrews.

"I think we made it difficult for ourselves, we could have played better but second half I think we played some good stuff, and it obviously helped when they went down to 10 men, it made it a bit easier from there and it is nice to get a 3-1 win, its brilliant for us."

Bradley to tell Wirtz to 'go easy' on Northern Ireland

Bradley played 76 minutes of Northern Ireland's victory in Luxembourg in what was his first start this season for club or country as he works his way back to full fitness following an injury sustained in pre-season.

"It's my first big minutes of the season after the little injury in pre-season so it was a tough night, but delighted with the victory, I thought we played really well at times," added the Liverpool right-back.

Up next for the 22-year-old and NI is a trip to Cologne to take on Germany, who were stunned by Slovakia in their opening game.

Bradley will come up against Reds teammate and the club's record signing Florian Wirtz, who he says he will message ahead of Sunday's game.

"It's going to be another difficult game but looking forward to it. We had a few jokes before we went away, not Whatsapps yet but I'll have to get into him tomorrow and tell him to take it easy on us," Bradley joked.

"He's an unbelievable player. I've seen that from the few weeks we've had together in pre-season, and we'll have to keep him quiet Sunday night."
