Klass, who made substitute appearances for the Rebels in both games against the Stones this season, came through the youth ranks at Fulham and Queens Park Rangers.
After his departure from Loftus Road, he joined Southend United in July 2017 and made his first-team debut in an EFL Trophy match against Gillingham. He also spent time on loan with Bromley. From there, he signed for Lewes and his performances at The Dripping Pan earned a move to Aldershot Town for the 2022/23 campaign. He joined Worthing for their second season at Step 2 last June.
Having risen through the ranks since joining in 2018, Adu-Poku signed a two-year professional deal with Watford last July. A regular for the under-18s, the forward has also made appearances for the under-21s.
He joined Southern League Division One Central side Kings Langley on a short loan in February and will be with the Stones for the next month.
