Valtti is a Finnish football club based in the town of Valkeakoski, competing in the Kolmonen, the fourth tier of the Finnish football league system. The club's full name is Valkeakosken Haka's reserve team, often referred to simply as FC Haka/Valtti. They play their home matches at the Tehtaan kenttä. As a reserve side for the historic FC Haka, Valtti's primary purpose is to develop young players for the senior Veikkausliiga squad. Consequently, their history is intertwined with the success of Haka's youth academy, producing numerous professionals over the years. The team's performances in the Kolmonen are viewed through the lens of player development rather than pure results, though they consistently field competitive sides. The atmosphere at matches is typically low-key, attended by dedicated local fans and scouts. Valtti serves as a crucial bridge between youth football and the professional game in Finland.
