The World Cup is well underway and the fixtures for the tournament's knockout stages are beginning to take place, but it hasn't been short of controversy - especially the amount of added time.
England's group opener against Iran saw 24 minutes of added time in the first and second half collectively after a number of stoppages. The eye-opening change has saw five-plus minutes additional time at the end of regulation time become the norm.
It comes after a change from legendary FIFA referee Pierluigi Collina who has, in effect, told referees to add every little amount of time the ball is out of play to be added on. As a result, we have seen nervy finishes and in Wales' case, two late goals dash their hopes of qualifying for the next stage.

The Qatar World Cup is a unique one. The Middle East has a host nation for the first time and also with the tournament being played in the middle of the league season.
This week saw the end of a football-packed day as the 1pm GMT kick-off's were scrapped as the respective nations in each group play simultaneously. The early kick-offs were played in sweltering conditions, despite the pitchside air conditioning.
Another first for this month's tournament was semi-automated offsides. This is computer generated and has already had a role in key moments at the competition.
Vincent Aboubakar scored a stupendous lob during Cameroon's 3-3 draw with Serbia, his nonchalant effort could've been due to a hint of offside in his line-bursting run. But thanks to the piece of technology, it meant that one of the great World Cup goals was not chalked off and allowed to stand.
How long is half-time at the World Cup?
Water breaks can be enforced by the match referees, however they haven't been used in the tournament so far. The 2014 World Cup in Brazil saw the introduction of the breaks midway through the first and second halves, lasting three minutes.
As is the case in the Premier League and across Europe, the interval last 15 minutes between the two 45 minutes. There could be arguments for longer breaks in the knockout stages after over 100 minutes of football being played during regular time, although there has been no case put forward yet.
England and USA booked their place in the Round of 16 on Tuesday, they will face Senegal and Holland respectively. Wales were dumped out of their first World Cup in over a half-a-century as they finished bottom of Group B.
