Ben Garner’s side have swooped to sign the full-back on a season-long loan deal from Fulham.
Sessegnon, 22, has been given the green light to leave the Cottagers on a temporary basis again to get some more experience under his belt.
Fulham academy graduate
Sessegnon has been on the books at Fulham for his whole career to date and has played 19 times for their first-team.
He played under the now AFC Bournemouth boss Parker, who was a hit during his playing days at Charlton, for a couple of years at Craven Cottage.
Sessegnon spoke to his ex-manager before deciding his new move and has opened up about his decision to join the South London outfit, as per the club’s official website:
“Not just him, I’ve had many conversations with ex-players and they just say it’s a real good club. They look after you well, treat you right and it’s a great platform to go and perform, so I thought, ‘that’s all I needed to hear’.
“I need to feel that energy, the love the fans have for the club and things like that are important to me. It just makes me want to play even better.”
He added: “I’ve come here twice (The Valley) and I’ve enjoyed myself here. The fans really get behind their team and it’s even better that I’m going to be playing under that, so I look forward to it.
“There have been big nights here that I’ve seen in the past so I look forward to being part of that.”
Charlton have been busy since turning to former Bristol Rovers coach Garner last month. They have delved into the transfer market to sign Joe Wollacott, Mandela Egbo, Eoghan O’Connell and Conor McGrandles.
Other Fulham news
Sessegnon is the first Fulham player to have been given permission to leave on loan for the new season.
The club has parted company permanently with the likes of Andre Zambo Anguissa, Jean Michael Seri, Alfie Mawson, Michael Hector, Fabri and Cyrus Christie since the end of the last campaign.
