Man City show no mercy

Premier League champions Manchester City began their FA Cup campaign with a 7-0 thrashing of Rotherham on Sunday but Fulham, battling to avoid relegation from the Premier League, were beaten 2-1 by fourth-tier Oldham.

Barnet ensured there would be a non-league presence in the fourth round with a 1-0 win away to second-tier Championship club Sheffield United.

Manchester City manager Pep Guardiola fielded a strong side for the visit of Championship club Rotherham, with Raheem Sterling, Riyad Mahrez and Gabriel Jesus all starting and playmaker Kevin de Bruyne returned from injury.

Sterling opened the score. Rotherham’s Semi Ajayi handed Man City an own goal, and further goals were scored by City’s Jesus, Mahrez, Nicolas Otamendi and Leroy Sane.

Elsewhere, Barnet beat Championship high-flyers Sheffield United thanks to Shaquile Coulthirst's 21st-minute penalty.

QPR beat Championship leaders Leeds by the same scoreline.

On Saturday, FA Cup holders Chelsea cruised to a 2-0 win over Nottingham Forest in what seems certain to have been Cesc Fabregas's final match for the Blues.

It was the same scoreline as Manchester United beat Reading to make it five wins out of five under caretaker boss Ole Gunnar Solskjaer. Arsenal won 3-0 at Blackpool, West Ham beat Birmingham 2-0, but Everton battled to see off Lincoln 2-1.

Saturday also saw Championship club Bristol City beat top-flight basement club Huddersfield 1-0.

Elsewhere, in an all-Premier League clash, Brighton won 3-1 away to Bournemouth.
