They can make history this afternoon by becoming the first twins to play against each other in the Premier League.
So just what will their proud parents Aidan and Janet make of it all?
Will, who joined Hull for £1million the day before the transfer deadline, told The Sun: “It's a tricky one for them!
“They want me to do well — but they want Mike to do just as well.
“I'm not sure what result they will be hoping for.
“Our other brothers Tom and Andrew will be there too, as will quite a lot of our mates. It's a nice bit of history."
