The 27-year-old England goalkeeper was sensational against West Ham.
They didn't create enough and were too static for Southampton's winner.
But, had West Ham played at their best, they still might not have beaten Fraser Forster...
Indeed, the Southampton goalkeeper was an absolute man mountain against the east London side on Saturday afternoon.
After his stellar display against Arsenal, Forster followed it up with more of exactly the same against West Ham.
Southampton fans haven't failed to notice the impact the 27-year-old's return from injury has made, with the Saints hitting form at exactly the same time. It's no coincidence.
Here, then, is how supporters reacted on Twitter to the England goalkeeper's performance at St Mary's!
Well, the weather is horrific, the trains late and Clattenburg a joke. But 3 points. And what more can I say about Fraser Forster? #saintsfc— John Cox (@JohnOfBasing) February 6, 2016
