Difficult to pick winner - Lineker

BBC Sport presenter Gary Lineker says it is so difficult to pick a winner at the 2014 World Cup.

For the first time, all eight group winners have reached the quarter-finals with Belgium joining Brazil, Colombia, Netherlands, Costa Rica, France, Germany and Argentina in the quarter-finals.

Former England striker Lineker says you can make a case for and against all of the eight teams that remain in the competition.
