Sinon stub callsFake argument

I had the following stubs running perfectly before

sinon.stub(console, 'log', () => {
    // Check what the arguments holds 
    // And either console.info it or do nothing
});

For example, adding console.info(arguments) inside there, would show me whatever console.log was getting.

With version 2xx I switched to callsFake:

sinon.stub(console, 'log').callsFake(() => {
    // Check what the arguments holds
    // And either console.info it or do nothing
});

This now longer works. console.info(arguments) has bazaar values, and nothing to do with what console.log is passing.

What am I doing wrong?!
