It’s his accent. He’s British, but quite plainly spoken. There’s quite a lot of “-ink” instead of “-ing” and “-ff-” instead of “-th-” (e. g. “nuffink” instead of “nothing”). The softer constanants are just characteristics of certain regions in the UK, but they can cause the sounds at the start/end of words to blur into each other.

To my ear, a fellow Brit, he’s perfectly clear, but I can see how it could be slightly tricky for a non-native.
