Coach Chris has watched Pompey twice recently and been impressed with what he's seen even though results haven't gone the way of Harry Redknapp's men.
Pompey are without a win in three league matches including a rare home defeat against Everton when they last stepped out at Fratton Park.
"Portsmouth can change their shape," reported Chris. "Generally they play four at the back in a flat 4-4-2 system but they can also play in a diamond shape.
"In the two games I've seen Berkovic played in one and looked to control the offensive part of midfield playing behind the front two and he is always a threat on the ball.
"But they have good ball players throughout like Quashie and Berger and what they've added is good options up front in the likes of Yakubu, Fuller and Lualua - mobile, quick players that are able to turn games.
"They are playing well this season. From what I've seen they are a good all-round team able to score goals with the quality they have in the side.
"They have made good progress in the Premiership and over a period of time have got used to the Premiership and learned to live with the quality and pace of the league."
Chris Hughton says we'll come up against a flexible, attacking outfit at Portsmouth in tonight's Premiership clash.
