Ever wondered what happens when you play football in the cold? Well, Liverpool midfielder Adam Lallana provided some chilling evidence from Sunday's 2-0 win over Southampton.
And apparently this is what happens to human feet when they have been sat on the bench for 79 minutes and then asked to run around for a bit.
Incredibly, the England international's toes appear to have turned a different colour to the rest of his feet.
The temperature on the south coast this weekend was only around 4 degrees Celsius, so one can only imagine what his feet would look like if it were even colder. Get some warmer socks, Adam!
