The latest Pompey news updates every day from the Pompey Sound News Desk.

There was chance after chance for Pompey during a dominant first half showing against Sheffield United at Fratton Park.

But despite being roared on by the home faithful, they were unable to turn the pressure applied into any goals.

And it came back to haunt the Blues when their opponents struck a winning goal through Andre Brooks in the 90th minute.

John Swift admitted that it was a frustrating afternoon for Pompey, as he felt they produced an otherwise encouraging display.

He said, It's very disappointing and the way we played, especially in the first half, meant the very least we deserved was a point.

To concede like that right at the very end from our own set-piece was gut-wrenching, having had so many opportunities to score ourselves.

It's very disappointing and the way we played, especially in the first half, meant the very least we deserved was a point.

We had played on the front foot and were aggressive at winning first and second balls.

The opportunities came from there.

The main frustration for us after the game was that we just weren't able to put the ball in the back of the net.

It wouldn't fall for us and there were a few moments when the ball bounced around the box and landed for their keeper.

There are definitely a few positives that we can take from that performance though and hopefully we can put things right on Tuesday.

Swift was making his first start for Pompey since the defeat at Bristol City on New Year's Day, having been limited to cameos in recent weeks.
