Portsmouth boss Avram Grant was unimpressed by Manchester United's performance, despite their 4-1 win at Fratton Park.

Wayne Rooney hit a hat-trick, while Ryan Giggs also struck on the eve of his 36th birthday. Pompey's goal came from the penalty spot, with Kevin-Prince Boateng scoring, although an offence did not seem apparent when Mike Dean pointed to the spot. Replays suggested Nemanja Vidic tugged Frederic Piquionne's shirt.

Grant lost his final game as Chelsea manager to United and suffered defeat again - although he took heart from the performance and feels his side have the ability to climb from their place at the bottom of the league.

"It was a strange game," he said.

"If I came from the moon and heard the result I would have thought Man Utd played great and Portsmouth was not so good but we played very well. I thought we played better. We created a lot of chances and conceded soft goals.

"Our goalkeeper almost didn't touch the ball and Tomasz Kuszczak made three great saves.

"Now our target is staying in the league, it won't be easy but it will be possible. The football was good and the spirit but there are things we have to do better - first to take points. When we play against teams close to us we need to win them."

Grant expects to make signings when the transfer window opens, adding: "In January of course we want to make the squad stronger and we will do."
