Charlton put another nail in Blackpool’s coffin as they eased to victory at Bloomfield Road on Tuesday night.
The Addicks hardly needed to get out of second gear, but adapted well to difficult playing conditions on a poor pitch, taking a first-half lead courtesy of Chris Eagles’ strike on his return to Lancashire, while Johann Berg Gudmundsson popped up with yet another screamer late on, adding to Simon Church’s long-awaited first goal of the season.
There were four changes to the side which suffered defeat at the hands of Blackburn Rovers on Saturday, with Joe Gomez, Alou Diarra and Church all returning to the starting lineup while Chris Eagles received his first start against his former club.
Yoni Buyens and Frederic Bulot dropped to the bench, while Tal Ben Haim and Igor Vetokele were given a rest.
It took just 12 seconds for the first shot to emerge and it came the way of the hosts when Andrea Orlandi curled a shot towards the bottom corner, forcing Stephen Henderson down to his right to make the save.
Meanwhile, the Addicks looked to make an immediate impact themselves with Tony Watt putting enough pressure on a tangerine shirt for the defender to head narrowly over his own bar before Gomez nodded the resulting corner just over.
With 20 minutes on the clock, Seasiders full-back Tom Barkhuizen tried his luck with a good-looking dipping effort which only marginally cleared the crossbar while his buccaneering run down the right five minutes later saw him cut into the box before dragging his shot wide.
The game was fairly stretched in the first half as the pendulum swung one way, then the other and it was from a swift Addicks counter-attack which saw the visitors take the lead just after the half-hour mark.
It all stemmed from a classy back-heel from Watt to play in Church, who in turn squared for Johann Berg-Gudmundsson 10 yards out.
The Iceland international saw his shot saved by Joe Lewis but former Seasider Eagles was on hand to tap home his second goal for the club and ensure Charlton a one-goal lead going into the break.
That strike also meant that the former Manchester United man has earned the rare distinction of scoring both for his old side against his new employers and vice versa in the same season.
The dangerous Barkhuizen threatened once again when his shot with the outside of his boot swerved wide from the angle as Blackpool enjoyed a bright start to the second half.
But just as the hosts looked to be making some headway, the Addicks struck a second just past the hour to put themselves in a commanding lead.
After good work from Gudmundsson on the edge of the box, he played a smart ball into the feet of Church who turned and rifled the ball into the roof of the net from eight yards to put daylight between the two sides.
In truth, the second goal killed off any remaining momentum which the game may still have held on the truly awful surface at Bloomfield Road as Guy Luzon’s men went through the motions on their way to a sixth victory in eight games.
The Seasiders did enjoy the odd foray forward which more often than not led to an over-hit cross or a speculative shot hit straight at Henderson, although substitute Bright Osayi-Samuel did test the reflexes of the Irishman on St Patrick’s Day with a decent effort 10 minutes from time.
The Addicks, however, were not finished and when sub Christophe Lepoint was chopped down on the edge the penalty area two minutes from the end, the travelling faithful watched expectantly as Gudmunsson stepped up to take it.
The winger has been in scintillating form from such positions in recent weeks and, of course the outcome was inevitable.
His free-kick flew delightfully over the wall and into the top right-hand corner for his ninth goal of a hugely impressive season and it was game over.
It could have got even better for the Londoners when Gudmundsson sent another effort curling just wide, while Lepoint glanced a header even closer past the post in injury-time as Charlton sailed to three more points which would see them jump a place in the Championship table to 11th.
