Mark Marshall understands Karl Robinson’s frustration with the Charlton manager’s future in doubt.

Wantaway owner Roland Duchatelet turned down his resignation before the Addicks’ defeat to Blackpool last week. 

Robinson has had no one to report to since the departure of former chief executive Katrien Meire in December - and Duchatelet’s desire to leave SE7 saw the club miss out on numerous transfer targets at the start of the year.

It’s left Robinson, who is the bookies’ favourite to take over at Oxford United, with a near impossible job of guiding Charlton into the Championship.

Addicks winger Marshall, who was signed by the Liverpudlian last summer, told News Shopper: “I wasn't aware of it [the resignation] until you just told me.

“At the end of the day, I can’t speak for him, I don't really want to speak on this situation because he’s his own man so he must have his reasons why he’s done that.

“Whatever he chooses to do, he has my blessings.”

Duchatelet told Robinson funds would be available in the January transfer window if Charlton were in a strong league position.

The Addicks were in the top six on Christmas Day, however, Robinson was only able to bring in three loan signings while rival clubs significantly strengthened.

The lack of investment resulted in star man Ricky Holmes joining Sheffield United, which was another blow to Charlton’s promotion hopes. They have won just four times in 2018.

Marshall, 30, added: “Of course, no one likes to be lied to, whether you're a player or a manager.

“When you feel like you’ve been deceived, it always gets your back up.

“He [Robinson] has his issues with the owner but we don't sit down and discuss that so hopefully they can be resolved between them.”

Duchatelet, who publicly stated the club was for sale in December, agreed a price with two parties last month.

And while it looked like a deal was close, further delays have angered Addicks fans and staff. But Marshall is refusing to blame Charlton's poor form on the continual takeover talk. 

He said: “That’s just an excuse. At the end of the day, when you go on the pitch, you’re meant to be focussed on what you're doing on the pitch.

“I wouldn't sit here and say ‘oh yeah, the takeover is having a massive impact on us’ because it has nothing to do with us.

“It’s not affecting us getting paid and it’s not affecting us training or on the pitch.

“So I wouldn't say it’s having a massive impact - that would be an excuse. We need to roll our sleeves up and try to get back to winning ways.”

Marshall played 66 minutes of Charlton’s goalless draw with Fleetwood on Saturday.

Robinson’s men never looked like scoring against a team battling the drop.

The bore draw extended Charlton’s winless run to four games - and in-form Plymouth are up next.

Marshall added: “The objective was always to get promoted. We’ve still got an opportunity to do that.

“But we haven't won in four so it’s important to get back to winning ways and you've got to always try and boost your own morale and the morale of your team-mates.

“We’re not a team that’s short of confidence because we’ve got good ability. It’s just that we need to get results in a results-driven business.

“There are 30 points to play for, we’re on 52, if we can get 19 or 20 points then I think we’ll get into the play-offs.

“History tells you 69 to 70 points in the last five years has got every team in the play-offs.

“It’s not galaxies away, we’ll be two points behind Plymouth with a game in hand if we win on Saturday. So we need to win sooner rather than later and then we can build from there.”
