Errors are costing us - Cotterill

Portsmouth manager Steve Cotterill has urged his side to cut out the defensive errors if they want to make the play-offs.Pompey looked set to pick up a point against Doncaster on Saturday until David Healy was given too much space to fire the visitors to a 3-2 win."If we want to start climbing the league we've got to stop giving away sloppy goals," said Cotterill."Nearly all the goals we've conceded this season have been down to individual errors rather than errors by the whole back four. We've got to get that out of our game as quickly as possible."
