Wolves striker Kevin Doyle acknowledges he is in for a difficult afternoon when attempting to get the better of Aston Villa defender Richard Dunne.
The pair are team-mates for the Republic of Ireland but will be in direct opposition in Saturday's Midlands derby, which can be seen live on Sky Sports 1 and HD1.
Doyle is aware of the attributes of Dunne, a Villa signing from Manchester City at the end of the summer transfer window, and expects a tough match at Molineux.
He said: "Richard is a very good defender as are all defenders are in the Premier League. So it is going to be another tough game.
"I was surprised when he left Manchester City as he had been their captain.
"We will say 'hello' beforehand and then we won't talk again until after the game.
"I don't know whether he has many weaknesses. He is a very good player.
"I am always on his side for Ireland and in training so I can't really say that I know him inside out.
"It certainly won't make it any easier for either of us. One thing I do know is that I won't be marking him at the set-pieces.
"We know he is a big threat in front of goal and that is something we will have to be aware of."
