Charlton decided to part ways with Holden on Sunday night after a disappointing start to the ongoing campaign.
With the transfer window nearing its end, it remains to be seen whether the Addicks will be able to appoint Holden’s successor before 1st September.
However, it has been claimed that Holden’s departure will not affect Charlton’s transfer activity.
And it is suggested that Charlton are expecting some incomings before the end of the window in the form of loans and permanent deals.
The Addicks could also sanction the departures of Jack Payne, Charlie Kirk and Conor McGrandles.
After a difficult first season with Charlton, Payne has fallen down the pecking order and is in the final year of his contract.
Kirk is also said to be attracting interest from League One outfits and Charlton are linked with several players in the transfer window.
