Newcastle manager John Carver was left frustrated by the defensive errors that cost his team in Saturday's 2-1 Premier League defeat by Arsenal.
An Olivier Giroud double put the Gunners two up at half-time, with both of his goals coming as a result of poor defending from set-pieces.
Moussa Sissoko pulled one back in the 48th minute for Newcastle, who were left to settle for a valiant defeat despite piling pressure on Arsenal in a frantic second half.
