Simon Grayson admitted he needs to improve Sunderland’s attacking capabilities after his side’s 2-0 defeat at home to Leeds United on Saturday.
The Black Cats missed the chance to take the lead when Lewis Grabban’s shot cleared was off the line by Liam Cooper and Leeds took immediate advantage to go ahead through Samu Saiz.
“I thought in the first 20 minutes we were the dominant team,” said Grayson.
“We played with real tempo, some decent quality, but there are fine margins in games – I don’t think Cooper knew too much about it, the ball hit his head and then hit the bar.
