Adam Armstrong's brace helped Blackburn to a comfortable 4-0 Sky Bet Championship win over 10-man Coventry at St Andrew's.
The Rovers striker took his tally to eight for the season in all competitions with goals either side of half-time, while on-loan Liverpool winger Harvey Elliott added a third and Sam Gallagher wrapped it up late on.
Coventry offered little in the way of return, aside from a red card for defender Michael Rose after a clumsy challenge in the box early in the game.
It was a lively and fairly even start to the contest with the ball moving fast along the surface thanks to several hours of persistent rain.
Armstrong, a former Sky Blues loanee, stepped up to send Marko Marosi the wrong way and give Blackburn the lead after 15 minutes.
Coventry looked shocked – their usual calm approach to playing out from the back hampered by a mixture of Rovers' aggressive press and being down to 10 men.
Lewis Holtby could have had a few goals. He saw a one-on-one well saved by Marosi – missing the subsequent rebound – and also wasted two free headers.
Armstrong and Brereton both had decent chances to put Blackburn two up, but Coventry went in at half-time only one goal down.
The home side's resolve crumbled shortly after the restart with Armstrong's second of the match.
The impressive Brereton played a smart ball into Armstrong, who had all the time in the world to pick his spot. Though Marosi got a hand to the shot, it was too powerful to keep out and the ball found the net after clipping the bar.
Elliott added a third after 62 minutes. A swift Blackburn counter saw Coventry's defence left wide open thanks to a key pass from Armstrong which found Brereton. He laid it across to Elliott, and the 17-year-old had enough time and composure to grab his first senior goal.
Elliott then turned provider as Blackburn wrapped up the victory with a fourth in the 88th minute.
A good passing move saw Holtby play Elliott down the left, and his ball across the box found substitute Gallagher who slotted home.
