Chem Campbell will be available for the Addicks’ trip to Oxford United on Saturday.
The 20-year-old joined Charlton on Wednesday, on loan from Wolverhampton Wanderers, and trained with his new teammates on Thursday and Friday.
Speaking ahead of Saturday’s game Holden said: “He’s had two light sessions with the group and is getting to know everybody. We’ve done a lot of research on him as a personality and like what we hear. As a player he can play right across the front line, carries the ball well, scores and creates, so we’re pleased to get him in. He’ll be available to be involved in the squad tomorrow.”
Holden added that the injured Richard Chin (groin), Scott Fraser (calf), Tyreece Campbell (ankle), Chuks Aneke (calf) and Miles Leaburn (ankle) are all likely to miss out.
Panutche Camará missed last weekend’s game against Port Vale with a foot injury. Holden said: “Pan has done a little bit in training and we’ll be monitoring him up to kick-off.”
The Addicks have had a difficult run of results but Holden remains confident the results will turn.
He said: "I was listening to the Ivan Toney interview [with Steven Bartlett] and you hear what has been done at Brentford and the culture they have created with Thomas Frank.
"Thomas has become a good friend of mine and a mentor, we’ve had good conversations. We're creating a culture here. We have a belief in the way that we operate. Our staff and players come in every day with an incredible work ethic, a humility, an open mind and a focus on improving. It takes time, we’ve had a big turnover in players and some injuries to key players but we'll keep focussed on continuing to improve each day and I'm certain the results will come."
The Addicks didn’t play a midweek game, so have had a full week training at Sparrows Lane for the first time since the start of the season.
Holden explained what his side had been working on: “All aspects of our game. We’ve digested the first few performances, looked at where we are excelling, where we are doing really well and also the other side of the game where we’ve come a little bit short. We’ve had lots of video meetings this week. It’s been the first week that we’ve had with no midweek game since the start of the season so we’ve been able to get a lot of work into the players which we’re pleased with.
“We’ve looked at set pieces and a number of things, defensively what we look like in possession of the ball. We’ve worked on all aspects with a focus on the basics of defending in and around our box and staying connected as a team.”
Charlton travel to an Oxford side sitting fourth in League One.
“They’ve won their last three in the league including away at Barnsley and Derby,” Holden said. “They’ve got a strong frontline with the wide players they have and [Mark] Harris, who runs in behind at every opportunity, [Billy] Bodin who plays in the pockets and [Cameron] Brannagan and [Marcus] McGuane in midfield. It will be a tough test for us, they are good on transition, they are good on the counter attack and have a lot of pace. We have to make sure we manage that part of the game but it’s a good game for us and I’m looking forward to it.”
