Robin van Persie has warned Arsenal to remain focussed if they are to beat local rivals Tottenham at White Hart Lane on Wednesday night. The Gunners missed a golden chance to close the gap on Manchester United by conceding a late penalty to draw with Liverpool at the weekend.
Holland striker Van Persie insists this throwing away winning positions must be stopped if the Gunners are to stay in touch with United ahead of their May 1 showdown at Emirates Stadium.
"This has happened too often, in my opinion," Van Persie told Arsenal TV Online.
"If you look at our history, when we are in front, when we are safe, when we have the three points in our pocket, we do concede goals.
"Some of them are silly goals, which we have to work on.
"We have to stay positive, but we really have to look at it because it is almost criminal to give away points like that."
