"Luke Williams is a terrific coach. I know a few players who have played for Luke. He is a nice fella.
"I have watched them quite a bit this season, they have a lot of rotations in the middle of the pitch, they stretch you with the wing-backs, and they have got three lads at the back who like to play football.
"They are a footballing team, that is the way they have played for a couple of years now, and they are really good at it.”
He added: "It should be a good game, two good teams who are desperate to win, desperate to get out of this division.”
