substitution

Clubs can bring squads of up to 25 players but only 14 can take part in the games which have unlimited substitutions.

Moments before the substitution was made, Dublin added: "Marcus Rashford is on fire tonight. You don't want to take him off."

Currently football people only think about time in quite a limited way: how long we have to hold on to the lead, when the first substitution should be made, when to throw the kitchen sink.

While Asian peers such as Taiwan, South Korea and Singapore shifted to export-led strategies in the 1960s - and began posting impressive growth rates of 8–10% annually - India chose to double down on import substitution.

It's not the first time they've booed my substitutions or my decisions.
