Sergio Aguero kept Manchester City on course to retain the FA Cup with the only goal in a disappointing fifth-round tie at Sheffield on Wednesday.

Aguero’s 23rd goal of the season in all competitions early in the second half ensured a routine win for the holders, three days after sealing back-to-back Carabao Cup triumphs at Wembley.

The Argentinian registered his 254th goal in all competitions for City in 367 appearances – one more than Wayne Rooney scored for Manchester United in 553 matches.

Pep Guardiola’s side crashed out of the FA Cup at the same stage two years ago when losing 1-0 at Wigan, but there was never a hint of an upset at Hillsborough.

Wednesday have slipped out of the Sky Bet Championship playoff picture after winning only one of their nine previous league matches and City rarely ventured beyond second gear.

Owls winger Jacob Murphy curled an early long-range effort wide and Aguero somehow failed to connect with Benjamin Mendy’s low cross six yards out.

But otherwise it was an uneventful opening – and things did not get much better.

Home captain Barry Bannan spurned a decent chance when over-hitting a free kick on the edge of the area and Gabriel Jesus was also wasteful, with a poor headed effort from John Stones’ deft cross.

Jesus should also have done better with Aguero’s diagonal ball over the top as Wednesday retreated into their own half and in the 32nd minute Nicolas Otamendi headed Riyad Mahrez’s free kick against the crossbar.

Stones met another ball in from Mahrez at the far post, but his downward header bounced over the bar as the first half ended goalless.

Wednesday, 3-0 down at half time on the same pitch against Derby on Saturday, will have considered the first part of their damage limitation exercise successful.

At the start of the second period Aguero’s effort was gathered by Joe Wildsmith and the Wednesday goalkeeper then brilliantly tipped Mendy’s thumping drive on to the crossbar.

Wildsmith pulled off another superb save to deny Bernardo Silva, but was culpable soon after when City broke the deadlock in the 53rd minute.

Aguero spun on to Mendy’s pass into the box and Wilder was only able to parry the Argentinian’s shot up and over the goalline instead of pushing it clear of danger.

There was a hint of offside to the goal and it may have been checked had a video assistant referee been in operation.

Wildsmith kept out Mahrez’s shot as City chased a second, while Wednesday had failed to muster an effort on target in the second half before Alex Hunt’s rare ball into City’s box just eluded fellow substitute Steven Fletcher.

Late substitute Raheem Sterling was sent on to finish the job and he was also denied by Wildsmith in time added on.
