World Cup 2018: 5 Things England Need To Improve To Beat Sweden

Substitutions can often be the difference between winning and losing in football, and is one of the manager's key jobs. From the first whistle to the last whistle, any impact Southgate may have from the touchline is limited, with the exception of his subs.

The manager's first substitution against Colombia came after 81 minutes, replacing Dele Alli with his Tottenham teammate Eric Dier. This made a lot of sense since the latter had missed the previous two games through injury, and had been struggling before the switch. However, Alli was clearly in pain before half time came, and should have been brought off much sooner than he was.

Similarly, after 88 minutes Jamie Vardy replaced Raheem Sterling in a swap that should have happened long before it eventually did. Sterling was clearly exhausted, unable to use his pace to trouble the Colombian defence as Vardy could have.

The final two subs came during extra time, understandably replacing Ashley Young and Kyle Walker after both seemed to pick up injuries, but had Rashford or Vardy been introduced sooner, there may have been no need for extra time in the first place.
