The hosts came into the World Cup as the tournament's lowest ranked team - 70th in the latest Fifa rankings. They are now into the last eight following their penalty shoot-out win over Spain. They scored eight goals in their opening two games, following a 5-0 win over Saudi Arabia and a 3-1 victory over Egypt. But have scored just once in their last 210 minutes of play - and that was from a handball penalty. Despite that how can you not back them making the semifinals? Next up for them are Croatia in Sochi.

Croatia
They have conceded just two goals from their four matches at the World Cup and should have put away Denmark in extra-time when Luka Modrić missed a penalty. The midfield duo of Modrić and Ivan Rakitic are world-class and could be a handful for the Russians.

England
England have only ever reached the World Cup semifinals twice, the last time was in 1990 when they lost to Germany on penalties. But everything seems to be falling in place for Gareth Southgate's side and the "football's coming home" crowd. Southgate rested seven players for the final group game defeat to Belgium so they should have plenty of legs for the potential extra-time and shoot-out against Colombia on Wednesday.
TAB odds: $3.50 (to reach final), $6 (to win it all)
Colombia
The South Americans reached the quarter-finals for the first time at the last World Cup where they were pipped 2-1 by hosts Brazil. They're outsiders to get past England on Wednesday morning but would most likely be favoured if they advance from there on until the final.
TAB odds: $7 (to reach final), $19 (to win it all)
Switzerland
It may be surprising to most that Switzerland are the third highest ranked team remaining in the tournament. The Swiss were sixth in the latest Fifa rankings and have lost once in the last year while drawing friendlies with Spain and Brazil. Switzerland have never reached the semifinals and last made the final eight in 1954 - they lost to Austria 7-5. They are the favourites to beat Sweden on Wednesday morning.
TAB odds: $12 (to reach final), $31 (to win it all)
Sweden
They lost to Germany, who didn't even make the knock-out stages! However, they are one of the hot teams coming into the round of 16 following a 3-0 win over Mexico. That doesn't matter. Sweden won't make the final.
TAB odds: $13 (to reach final), $41 (to win it all)
