Angry Charlton Athletic supporters have promised not to spoil the party for a club looking to celebrate promotion at The Valley.

Supporters have been using home games to demonstrate their frustration with the Belgian owner Roland Duchatelet who has taken the Addicks from Championship to League One.

Matches have been disrupted and delayed with fans throwing beach balls on to the pitch and lighting flares.

Visiting Burnley have already guaranteed a £100million journey the other way – promotion to the Premier League – and they are looking to make the match a celebration – but they also have unfinished business.

Burnley manager Sean Dyche, back in the Premier League at the first time of asking, said: “We’ll be focused on Saturday I can assure you. We were runners-up last time don’t forget. So we want to win it. That will be the focus. We’ll go and win it, that’s our job. Let’s enjoy it now because this is another part of history for this club and history runs deep here.”

Burnley fans have expressed concern that Charlton’s last Championship match (KO 12.30) could result in a tumult of protest, an abandoned match and their ambitions to stay in top spot thwarted.

But the Coaltion Against Roland Duchatelet (Card) has declared that any planned protests on Saturday will not interfere with the match.

A spokesman said: “We have no intention of preventing the completion of this match and neither will we be encouraging others to do so.

“This does not mean that we will not be protesting on the day. We will. But we will respect the integrity of the competition and the ambitions of the visiting club.

“Given the level of anger about the situation at The Valley, we cannot speak for every Charlton supporter and we make no claim to do so. However, our aim is to destroy the regime wrecking our club, not the game itself.”

Meanwhile, Charlton players are beginning to mull over their futures. Goalkeeper Nick Pope and captain Johnnie Jackson have both said they will stay; Iceland international Johann Berg Gudmundsson is postponing a decision until after the Euros and Morgan Fox has been linked to a move to Birmingham City.

Mixed emotions

• Jordan Cousins was left with mixed emotions after picking up the club’s Player of the Year award for the second successive season on Sunday evening.

“It’s nice to win the award again, it’s another nice thing to have on my CV but ultimately it’s not been the best of seasons for the club, which is obviously a big downside,” said Cousins .
