Collins Sichenje joined the Addicks in February 2026 from Serbian SuperLiga side FK Vojvodina for an undisclosed fee.
Born in Butere, Kenya, Sichenje started his career with Green Commandos before moving to Kenyan Premier League side AFC Leopards in September 2019.
Following a brief spell in Greece with PAOK B, the centre-back returned to AFC Leopards before joining Swedish top-flight side AIK in 2022.
After spending the 2023/24 campaign on loan with Finnish outfit KuPS Kuopio, he joined FK Vojvodina on an initial six-month loan, with the move made permanent in September 2024 following an impressive start to life in Serbia.
Sichenje has represented Kenya eight times to date, having made his debut in a 1-0 win over South Sudan in March 2021.
