Ben Foster believes that goalkeepers such as Ederson and Alisson Becker have raised the bar in the position.

Most goalkeepers are judged solely on their shot stopping ability.

However, Alisson and Ederson are known for their ability on the ball, as they are able to come out to stop counter attacks and can complete short passes with their fee while under pressure.

Foster believes such an ability is changing how all goalkeepers will be expected to perform in the future.

"I think the best way to judge a goalkeeper is to watch all of the goals that he concedes and make a balanced opinion of whether that goalkeeper could do much about the goals or not," he told Squawka.

"A goalkeeper that exudes confidence and calmness is a massive attribute too as it can have a huge positive effect on the other players on the team.

"[Ederson and Alisson] have raised the bar in what people now expect from the goalkeeper.

"They're both amazing and [there is] very little difference between the two! [They are] probably the two best goalkeepers in the world right now."
