The race to win the Golden Glove award is hotting up and Alisson faces stiff competition as he bids to retain his crown.
The Liverpool goalkeeper has nine Premier League clean sheets, a total shared by Sheffield United's Dean Henderson and Nick Pope of Burnley.
Kasper Schmeichel of Leicester City and Watford's Ben Foster stand only one behind with eight shutouts.
With the leaders conceding 15 goals so far, Alisson, who kept 21 clean sheets in 2018/19, is well-placed to win the award, presented by Cadbury, again.
The Brazilian's quest to become the leading contender for a second season is all the more impressive given injury and suspension have restricted him to 17 Premier League appearances.
Indeed, Alisson's nine clean sheets have come in his last 10 starts.
Not only does Alisson have the highest save percentage in the league this season at 87 per cent, he is also the top goalkeeper when it comes to Opta's new Stats Perform Goalkeeper Index.
Using the Index, Opta can simulate how each goalkeeper would perform if they faced all 2,108 of the shots faced by goalkeepers in the Premier League this season. This provides the number of goals that each goalkeeper would be expected to concede.
