Lee Boywer was disappointed that Chelsea decided to recall Conor Gallagher from his loan at Charlton.
The 19-year-old scored six goals in 26 appearances for the Addicks and quickly became a fan favourite for has excellent performances.
Bowyer has revealed that Gallagher’s exit has now forced him into trying to find a replacement.
Speaking to the club website, Bowyer said: “I’m disappointed. I didn’t see this coming if I’m honest, which makes it harder to take. At the end of the day, though, we have to move on.
“He’s been a credit and a pleasure to work with. He’s come in and put his body on the line every single day. He’s scored us goals and helped us win games.
“For someone so young, he’s a great talent to work with. He’s come in, learnt and he’s going back a better player than we received and that’s what our job is – to improve players.
“The most important thing now is that Conor goes on and progresses in his career, and we’ve got to move on and try and find a replacement.”
Charlton have recently had a bid accepted for Peterborough’s attacking midfielder Marcus Maddison while they also have other deals in the pipeline.
The club’s executive chairman Matt Southall tweeted: “All the best for the future Conor. Now back to work… deals pending.”
