Colombia finally broke down a stubborn DR Congo side on Tuesday to secure a 1-0 win that guaranteed their place in the World Cup knockout rounds.

Victory in Guadalajara, courtesy of a 76th-minute goal from Daniel Munoz, took them top of Group K with six points -- two clear of Cristiano Ronaldo’s Portugal with one game to go in the first round.

Portugal, held 1-1 by DR Congo in their opening match, earlier hammered Uzbekistan 5-0 in Houston, with Ronaldo scoring twice.
