Penalty to Portsmouth! Diouf hangs out a leg and trips Johnson and its a clear penalty.

The game has been drifting towards a finish for the last half hour or so and Sunderland are surely going to regret their missed first half chances and lacklustre start to the second period.

Superb goalkeeping from Fulop as Ferdinand and Nosworthy go for the same ball but the keeper dives in at the right moment to keep the ball away from a ready to pounce Defoe.

There has not really been a chance for the last ten minutes or so with neither side really looking like breaking through to claim all three points.

We are into the final ten minutes but the game has stagnated again with the sides cancelling each other out after the string of changes.

The home crowd are growing frustrated as their side look for the perfect through ball but Campbell and Distin are looking pretty comfortable.

Cisse and Defoe are the men who look most likely to win this game for their respective sides and this time it is the Black Cats striker who threatens as he forces a sliding block from Distin.

As we enter the final 20 minutes this game could easily go either way with neither side appearing to grab the upper hand.

Goal disallowed! Reid again the creator as he crosses onto the head of Cisse who beats James but the linesman 's flag was up - correctly - for offside against the Frenchman.

Finally we have a game on our hands as both sides go in search of goals to give themselves the advantage.

Tony Adams is looking for his first win as Portsmouth manager and his players look hungry to deliver it to him in this second half with Defoe and Diarra becoming influential.

Belatedly Sunderland have switched back into some sort of gear and they have all the work to do again.

Defoe has sparked into life all of a sudden as he robs Ferdinand on the edge of the box and again his early shot skids inches wide of the post as Pompey try to turn the screw.

Sunderland are giving themselves no-end of problems now as Reid doesn't look behind him as he plays the ball blindly into Defoe's path and he flashes a shot just wide of the far post.

Pompey look a little brighter already here with Kranjcar working Bardsley hard and his cross is only a fraction too high for Crouch.

There are going to be just two minutes of injury time somehow - Cisse and Whitehead are back in the action.

Defoe is back without a problem but Cisse appears to be in a lot of trouble with his ribs - now Whitehead is down and the physio is back on. A stop-start last five minutes or so here.

Light relief for the visitors as Kranjcar is back on after minor treatment - but now Defoe is down and so is Cisse for Sunderland.

More problems for Portsmouth now as Kranjcar takes a heavy fall after an aerial challenge from Bardsley and rolls of the pitch clutching his shoulder.

Sunderland fail on three occasions to clear a corner and eventually the ball drops to Distin who bobbles the ball tamely into the arms of Fulop.

Portsmouth started brightly but that early goal seems to have taken them out of their stride and they are yet to recover to any extent.

Andy Reid feeds another beautiful ball into the channel and Cisse in carbon-copy fashion races past Campbell but this time the shot is saved by James.

The game has slowed and become scrappy pretty much since Cisse scored with Richardson and CIsse the only attacking players on either side to impress.

Jermain Defoe has not even had a touch, let alone a sniff of goal so far and that is great testament to the Sunderland back four and midfield who have been impressive in their pressing of the ball.

Portsmouth are on the back foot now and are finding it really hard to get themselves into the game with Lassana Diarra being kept peculiarly quiet.

Djibril Cisse is stealing the limelight here as he bemuses Campbell again before forcing James to full stretch to tip his curling effort over the cross bar.

Cisse is back and looking a lot better and he immediately lays the ball off for Richardson who strikes fiercely against the foot of the post - so close for the former Man Utd man.

Cisse - with an extravagant Mohican haircut - is clutching his ribs as he writhes on the floor and looks to be in a bit of trouble as he hobbles off for treatment.

Half chance for Kranjcar as Ferdinand and Nosworthy rush to Crouch the ball drops to the Croatian but he fails to keep his volley down and Sunderland survive.

Roy Keane could not have wished for a better start in his 50th Premier League match in charge of the Black Cats and it has certainly given the home fans a lift.

The visitors are back on the front immediately and Crouch twice goes close with headers from Belhadj and Diarra crosses.

A very lively opening on Wearside with Portsmouth holding the upper hand early on as Kranjcar wins a free-kick.
