Liverpool boss Jurgen Klopp believes not introducing five substitutes will impact on the England team next summer.

"I'm pretty sure we will discuss it again, as all the teams have to play every three days from now and everyone will feel the difference to other seasons.

"And next summer it will become a problem for [England manager] Gareth Southgate because most of the players he wants to pick will have played three times a week all the time.

"So Gareth will get what we can give him and if we stick with three subs then he has the problem then. So it's an FA problem, in my understanding."
