This is Belgian side Royal Standard de Liège’s special new 125th-anniversary shirt from adidas.
Featuring a special crest - with “1898[-]2023” detailing - the red shirt with white horizontal stripes sees the partner branding keep to this dual-colour palette, with the gold of the said club badge the only departure.
Home matches and a proportion of away trips in the 2023-24 Jupiler Pro League will see the kit completed with matching red shorts and socks.
