The Round of 16 in the 2014 World Cup in Brazil is done and dusted, but not without its ups and downs. We take a look at some of the plays which eventually decided matches:Brazil keeper Julio Cesar saved two penalties in the shootout win over Chile in Belo Horizonte which ended 3-2 in favour of the hosts after the match was tied at 1-1 after extra-time.It was still 0-0 between Colombia and Uruguay at the Maracana in Rio De Janeiro. But that was before James Rodriguez decided to take matters into his own hands in the 28th minute. The 22-year-old forward scored one of the contenders for goal of the tournament with a thunderous volley to set Colombia on course, with Los Cafeteros eventually winning 2-0.As the France-Nigeria match looked set to go into extra-time with the scores still 0-0 in Brasilia, French midfielder Paul Pogba's header from a corner in the 79th minute got the crucial breakthrough against a stubborn Nigerian defence. France went on to win the match 2-0.With the scores level at 1-1 in second half stoppage time in Fortaleza, Netherland winger Arjen Robben appeared to go down easily in the box under Mexico defender Rafa Marquez's challenge in the 92nd minute. However, the referee pointed to the spot and Klaas-Jan Huntelaar stepped up to bury his spot-kick as the Dutch won the game 2-1. Was that penalty justified or was it a dive? The debate goes on...Angel Di Maria latched on to a Lionel Messi pass in extra-time to break Switzerland's resistance in the 118th minute as Argentina scraped through with a 1-0 win in Sao Paulo.Substitute Andre Schurrle produced a moment of magic with a back-heel flick in extra-time to open the scoring for Germany in the 92nd minute, after normal time had ended goalless. Despite some late pressure from Algeria, the Germans held on for a 2-1 win in Porto Alegre.Romelu Lukaku, who is usually in the starting XI, was on the bench for Belgium as they took on USA in Salvador. But the Chelsea man was brought on at the start of extra-time with the scoreline still 0-0 and went on to stamp his authority on proceedings. The striker was at the heart of the move that got the Belgians their opening goal through Kevin De Bruyne and then scored one himself as Belgium ran out 2-1 winners.Extra-time in Recife had ended level at 1-1 between Costa Rica and Greece. But Costa Rica's Keylor Navas was ready to take the bit between his teeth in the shootout. The goalkeeper made a fantastic save to keep out Greece striker Theofanis Gekas' penalty as the Central Americans won the shootout 5-3.
