Barnsley boss' admission after his side's defeat to Portsmouth

The Blues delivered a fine performance in their 4-2 victory and marched into the fifth round of the FA Cup.

Kenny Jackett’s men fully deserved their success against the Tykes with Ben Close, John Marquis, Ronan Curtis and Christian Burgess all on the scoresheet.

But Struber was frustrated with Barnsley’s display and felt they were nowhere near the standard of a second-tier outfit.

The head coach told the Barnsley Chronicle: ‘I am unhappy and disappointed. The opponent’s spirit and energy showed us what you need in the FA Cup. Our spirit and energy was not enough to win the game.

‘I must look back at the game on a video. But now I am unhappy with many situations. We needed too long to get into the right position.

‘We lost so many simple balls in the first and second half. It was not like a Championship team. The performance in the whole game was not enough and we have to speak about this game with the boys.

‘When we get a goal, our attitude was not like a winner’s mentality. We have to congratulate the opponent.

‘I felt sorry for our fans. It is a long journey and it is very disappointing for us, for the fans and for the club. We are all very disappointed.’

Both Burgess and Marquis’ goals for Pompey arrived from corners whipped into the box by Steve Seddon.

Struber conceded it’s an ongoing issue that’s sending Barnsley towards Championship relegation.

He added: ‘It is a problem again. We are not clear on the man. We have a plan for man-marking but, when we don’t do our job, it is not enough and we lose two goals from set pieces. It is an angry situation.’
