The Sunderland defender has been talking tactics ahead of the North East derby.
Sunderland captain John O'Shea has demanded that his show a ruthless edge against Newcastle United this weekend.
The Black Cats have struggled for goals throughout the campaign so far, but O'Shea has urged his forward line to be more accurate on Sunday.
Sunderland have only won two of their first 16 Premier League matches and the Republic of Ireland international feels that they will need their attackers on top-form in the North East derby if they are to improve this record.
“We just need a bit of a killer instinct all round the pitch to make sure we come away with three points instead of a draw," he told the Sunderland Echo.
"We’ve been very solid, though, and close to winning lots of matches. But you can talk about these things, you have to go out and do them on Sunday afternoon when there’s going to be lots of people in the stadium willing you to have a bad game."
Sunderland's goalscoring issues have seen them score just 14 goals in the league this season, in what has been a worrying opening to the campaign.
The side have only been beaten four times to date, but they are still only two points above the drop zone because of their failure to convert their opportunities.
Steven Fletcher is the only player in Gus Poyet's squad who has scored more than two goals in the league this campaign and they will need to improve on this if they are to get anything from St. James' Park.
