It was an afternoon to forget as Coventry City lost 5-0 to West Bromwich Albion at The Hawthorns.
The Sky Blues went behind after only 31 seconds through Diomansy Kamara - seconds after Adebola had a chance at the other end to open the scoring.
Kamara added another from the penalty spot before Jason Koumas scored the third as the Baggies dominated.
Kevin Phillips and Paul Robinson wrapped up the points in the second half as Coventry - who before the game had the second best defensive record in the Championship - crumbled.
Micky Adams made one change to the side which travelled to The Hawthorns, with Marcus Hall coming into the side for the suspended Leon McKenzie.
The move meant that Hall was reinstalled at left-back, with Clive Clarke moving to central midfield. Colin Cameron moved out wide.
West Brom also made one change, with Kamara replacing Zoltan Gera on the right hand side of midfield.
The Sky Blues suffered from a nightmare start when they went behind after 31 seconds. Koumas' through-ball found Kamara, who beat Marshall to the ball before taking around the keeper and walking it into the goal.
But Coventry didn't let their heads drop and after seven minutes, they could have pulled it back to level terms when John connected with Currie's cross, only for Hoult to save at his near post.
Five minutes later, it was Marshall who was called into action as he saved from Phillips at point-blank range, before at the other end, Adebola cut the ball back into the area but Hoult collected Doyle's effort.
Hartson fired wide on 23 minutes as the Baggies searched for another, before the lively-looking Koumas fired a free-kick after the corner of the goal.
It went from bad to worse for the Sky Blues on 33 minutes, when the home side were awarded a penalty after Hall was adjudged to have fouled Kamara and from the resulting spot-kick, the Senegalese striker sent Marshall the wrong way for his second of the game.
Doyle went into the book for a foul on Koumas a minute later as Tony Mowbray's side exerted more pressure, but the result free-kick sailed well over the target.
Page was booked for a foul on Kamara - his fifth of the season - before Coventry threatened as Clarke's shot was deflected wide.
The third goal that West Brom were so desperately trying to find arrived on 39 minutes - and it was disappointing that it came from a Sky Blues corner. Phillips broke from City's penalty area and played a defence-splitting pass to Koumas on the left-hand side, who cut inside and struck his shot, which squirmed under the body of Marshall and went in.
Frustration was getting to the Sky Blues players and Clarke was the next to go into the book on the stroke of half-time - along with Kamara - and Duffy joined them moments later for a deliberate handball.
The second half started as the first had ended - with West Brom dominating. Hartson beat Ward to the ball in the air to force Marshall down to save.
The Sky Blues were awarded a free-kick when Adebola was brought down on 53 minutes and from the resulting set-piece, Clarke saw his shot deflected over the crossbar.
It was a becoming a rout at the Hawthorns and with 57 on the clock, Mowbray's team made it 4-0. Phillips picked up a loose ball from Currie in the midfield and the former Sunderland man finished beautifully from the edge of the box past the outstretched hand of Marshall.
Ellington replaced Hartson a minute before the hour, before the Sky Blues made a double substitution - Mikkel Bischoff replacing Ward and Kevin Kyle coming on for Currie on 62 minutes. It was the Dane's first appearance for Coventry since signing at the Ricoh Arena from Man City in the summer.
Cameron lifted his shot inches wide of the post on 70 minutes after finding himself one-on-one with Hoult before Chris Birchall replaced Clarke four minutes later. West Brom also made a change, with Clement replacing star-man Koumas.
West Brom wrapped up the game with their fifth strike of the afternoon as Jonathan Greening turned Duffy inside-out before crossing to Paul Robinson, who headed it past Marshall for his first-ever goal at The Hawthorns.
A mention must be made for the Sky Blues supporters, who sang for the entirety of the game, despite being behind from the off.
