It was tight apart from the set-pieces - Mousinho

Portsmouth boss John Mousinho has ruled set-pieces as the deciding factor as his side fall to a 4-1 loss to Premier League leaders Arsenal in the FA Cup.

Three of the Gunners' four goals at Fratton Park came directly from corners, with the first off Pompey midfielder Andre Dozzell for an own goal.

Gabriel Martinelli helped himself to two near post headers as he claimed a hat-trick taking the number of goals Pompey have conceded from corners and free-kicks this season to 18, in all competitions.

"You've got to take the last little spell out of the game with 10 men and also towards the end getting a bit tired - but I thought we were right at it," Mousinho told BBC Radio Solent.

"I thought we were well in the game, I thought for parts we were the better side.

"The difference in the game was the set-pieces.

"The delivery [of set-pieces from Arsenal] is excellent and the way they attack the ball with aggression is brilliant, but we just didn't match that. We didn't match the level of intensity and aggression that was shown.

"It was pretty tight apart from the set-pieces. They are part of the game so we've got to be better at them."
