Gylfi Sigurdsson played in Walcott and as the winger looked to round the goalkeeper, Alisson somehow clawed the ball out of his path and hung onto it.

Another fan said: "Alisson really showing his worth today absolutely class keeper."
A third said: "Alisson might be the best keeper in the league."
"Alisson Becker is best keeper in league by a mile," another added.
