Republic of Ireland international Jason Knight was handed the captain's in Wayne Rooney's first game in permanent charge of Derby County, but couldn’t prevent the Rams from a 1-0 defeat to Rotherham. 

The 19-year-old Knight, who scored six goals in 31 appearances last season, joined Derby from Cabinteely in 2017 and broke into the senior squad at the beginning of the 2019-20 season and has been linked with a move to Burnley. 

Knight has represented Ireland at every age-group since U15 and made his senior debut as a substitute in the Nations League game against Finland last October. He made his first senior start in the 0-0 draw at home to Bulgaria the following month. 

Today’s defeat however saw Derby drop down to second bottom, behind their opponents on goal difference with Jamie Lindsay firing home for Rotherham four minutes from time 

It was far from an ideal start to his reign for Rooney, who pulled no punches in his assessment of his side's under-whelming performance. 

"Today Rotherham outfought us," said the former England captain. 

"Our quality on the ball and our concentration levels weren't where they should be. That's the disappointing thing and, if I'm being honest, I don't think we deserved anything from this game. 

"Obviously, the preparations over the last few weeks have been hampered because of Covid but that's not an excuse for today's result. The lads looked good and sharp in training the last few days. 

"We knew Rotherham press well and would be a tough game, but we didn't seem to have that quality on the ball. We seemed to lack edge and let ourselves down when in possession and under pressure. 

"We know we can play better than we did today, but I don't think we even deserved a point today. 

"We gave silly free-kicks away in dangerous areas and that's what Rotherham were looking for as it's a big part of their game. 

"But those free-kicks allowed them to send defenders up and cause issues."
