The player Davis reminds me most of is Matt Oakley.
Unspectacular, steady, doesn't tend to stand out when we play well, or when we play poorly. Never found wanting or seeming to be exceptional.
He is however a vital cog in the machine, only really noticed when he isn't playing at all.
Without him we would be worse off and his efforts have been vital in stabilising us back in the top flight over the last 5 years. He was a brilliant signing and remains a key player.
