West Ham United whizkid Josh Cullen will stay with Charlton Athletic until the end of the season.

The midfielder will now try and help Lee Bowyer's side avoid relegation with nine games remaining in the Championship season.

"It was quite straightforward for all parties involved," Cullen told Charlton's official website.

"There is still a job to be done. There are nine massive games to go and it was always in my head to be a part of that. You want to finish what you started and it's been a long journey up until now, but it's not finished.

"It was a straightforward decision and I feel like I owe it to the club. The fans have backed me from day one and been brilliant to me."
