Five games, five wins, fifteen points. It is the cleanest line in football and right now eight clubs across four countries can claim it.
Germany's trio
Borussia Dortmund have strung together five consecutive wins in the Bundesliga, a run that puts them at the top end of the form table regardless of league position. One tier down, Hertha BSC have matched that exactly in 2. Bundesliga, winning all five of their last outings. Borussia M'gladbach have also won five straight, though that run has come in club friendlies rather than competitive fixtures, a different context but a spotless record all the same.
Brazil's double
In Brazil, Flamengo have won five in a row in the Brasileirão Serie A, the kind of streak that tends to shift title conversations. One division below, Athletico have done the same in Serie B, also five from five.
England and beyond
Manchester City have won their last five in the Carabao Cup, while Leeds United have reeled off five straight victories in the Championship. Over in Belgium, FCV Dender have matched the feat in the Challenger Pro League.
Eight different clubs, eight different competitions, the same scoreline across the last five matches: WWWWW. Streaks like this rarely last forever, but for now these are the sides nobody wants to face.
